We present an open-source online dictionary editing system, Ve
rdd, that offers a chance to re-
evaluate and edit grassroots dictionaries that have been exposed to multiple amateur editors. The
idea is to incorporate community activities into a state-of-the-art finite-state language description
of a seriously endangered minority language, Skolt Sami. Problems involve getting the community
to take part in things above the pencil-and-paper level. At times, it seems that the native speakers
and the dictionary oriented are lacking technical understanding to utilize the infrastructures which
might make their work more meaningful in the future, i.e. multiple reuse of all of their input.
Therefore, our system integrates with the existing tools and infrastructures for Uralic language
masking the technical complexities behind a user-friendly UI.
1 Introduction
We present an open-source dictionary editing tool
called Ve
. The tool has been and currently is under
active development to cater for the needs of Skolt Sami (ISO 639-2: sms) speaking language community
and their on-going project on modernizing a Finnish-Skolt Sami paper dictionary (see (Alnajjar et al.,
2020)). Although Skolt Sami is severely endangered with its 300 native speakers (Moseley, 2010), a great
deal of NLP tools have been developed for it over the past decade; such as finite-state based morphological
analysers and generators in the GiellaLT repository (Moshagen et al., 2014), XML and MediaWiki based
online dictionary (Rueter and H
ainen, 2017) and most recently a universal dependency treebank
(Nivre et al., 2019). However, due to the pluricentric nature of the language (see (Rueter and H
2019)), these tools are far from perfect. One of the core design principles of Ve
rdd is to bring these tools
closer to non-technical community members editing a high-quality dictionary.
Building dictionaries is an essential part of resource creation when working on endangered low-resource
languages. At the same time, lexical resources are an important part of the work done on computational
morphological descriptions, such as finite state transducers. We argue that these lines of work have
not traditionally entirely met each others. Traditionally the distinction may have been easier, as some
dictionaries were intended to be printed, and others served computational infrastructure such as spell
checkers. Nowadays, however, all dictionaries are born digital. Much of the dictionary writing work,
often connected to traditional linguistic descriptions and the needs of the communities themselves, is still
customarily done by hand using ordinary text processing software.
In other contexts, various other tools have been used. SIL FieldWorks (Baines, 2009) has been popular
among many language documentation projects, although it clearly is not suitable for all projects and lacks
many functionalities (Rogers, 2010). Commercial tool TLEx (Joffe and De Schryver, 2004) has also been
used, although we personally would not prefer attempts at the use of commercial proprietary software in a
language documentation context. These also all represent traditional, installed software that do not allow
easy cooperation on a larger team level. A project that comes closer to our work is Lexonomy (M

2017). A central difference here is that our work connects the formal computational descriptions to the
dictionary editing process, whereas other projects seem to principally offer a digital environment for the
traditional dictionary making itself.
Besides editing dictionaries, one important purpose of Ve
rdd system is to allow combining information
from different dictionaries. Many parts of lexical information that we want to present combines various
sources. For example, etymological data by definition involves several dictionaries and their intercompari-
son. Similarly dialect dictionaries are inherently connected to the lexicons of their corresponding standard
In many cases such specialized dictionaries may be practical to represent as distinct works, but still
their connections to the other resources are myriad, and essential for the whole enterprise. Ve
rdd makes
it possible to add these relationships between different entry and relation types. Resulting specialized
dictionaries can, if wanted, be exported, but this way we avoid repeating the shared parts of the entries
and can minimize duplicate efforts.
2 Ve0rdd System
In this section, we describe the major features implemented in Ve
rdd. Ve
rdd is developed in Python using
Django framework. Django has been picked as it scores high when compared to other web frameworks in
terms of quality attributes (Plekhanova, 2009).
When building Ve
rdd, modularity was constantly kept in mind to allow the system to be extended,
incorporated into other systems or used for other languages. Currently, the system keeps track of the
following elements in a dictionary: 1) lexemes, 2) their inflectional paradigms, 3) any relevant external
links to them, 4) relations between two lexemes, 5) sources that backup these relations (e.g. other
existing dictionaries), and 6) examples and 7) metadata to lexemes and relations. Nonetheless, we
are considering adding dialectal transcriptions and locale information to lexemes, which, in addition
to preserving this information, would support geolinguistics studies of these languages and facilitate
developing computational models for processing dialects (c.f. (Partanen et al., 2019)).
rdd supports importing existing dictionaries in XML and CSV formats or from the Akusanat
MediaWiki dictionary (H
ainen and Rueter, 2018) directly, this is to allow a smooth transition for
editors to the tool without the need to input the data manually. In the import process, Ve
rdd takes care
of wrong character encoding by mapping wrong variations into correct versions. This unification of
characters is important as many of the special characters used in Skolt have either emerged in the Unicode
standard recently, have wrong, similar looking Unicode characters or are impossible to type without an
appropriate keyboard layout. This has lead to a high degree of inconsistencies of the characters used to
write Skolt Sami, even if the text has been saved in UTF-8.
Figure 1 shows the front page of Ve
rdd, in which users can use the advanced search functionality to
filter lexemes by lemma (fully, partially or matching a regular expression), language, source they appeared
in, whether they have been verified and so on. Additionally, they can sort the result by their assonance and
consonance which could help in discovering lexemes sharing an inflectional form. Users can access, edit
or delete lexemes from this page. Furthermore, users can download the entire result of the search query or
enter the bulk approving mode where they can tick a checkbox to confirm that the information associated
with the lexeme is correct, which will highlight the approved lexemes in green as illustrated in the figure.
A similar search interface also exists for relations.
rdd utilizes the Skolt FST (Rueter and H
ainen, 2020) through UralicNLP (H
ainen, 2019)
to produce inflectional paradigms. The transducers are built on HFST (Lind
en et al., 2013), which makes
it easy to integrate transducers for other languages as well. The most common paradigms are displayed
under the mini-paradigms section; nonetheless, users can access the full list of generated word inflections
by clicking on the “See all miniparadigms” button. Users have the ability to add new inflectional forms
and, in case of a wrong inflection produced by the transducers, they can correct it by adding a form that
overwrites the wrong word form. Corrections of this nature are monitored closely and used as a feedback
to update the transducers.
The system organizes the lexicographic data into a list of lexemes that contain all the relevant infor-

mation to the lexeme itself (such as inflection, language, part-of-speech) and relations in between two
lexemes. The relations (such as derivations, compounds and translations) linked to a lexeme are also
shown in the lexeme view interface. Sources (e.g. other dictionaries) that support the defined relation,
along with example sentences and metadata that are specific to the relation, are presented alongside the
relation. The sources functionality makes it possible to compare the different dictionaries that have been
imported into the system.
Users can edit, delete or supply Ve
rdd with new information regarding any of its elements (e.g. lexemes,
relations, sources . . . etc). Ve
rdd keeps track of all versions of instances along with who changed them
and when, to mitigate introducing inaccurate information and losing the ability to revert back to the correct
Once a user has finished checking or processing a lexeme, they can navigate to the next or previous
lexeme using the navigation lists at the sides of the lexeme information. The navigation list depends on
the search query the user defined during their filtering phase. This gives them the ability to move form a
lexeme to another effortlessly without going back to the search results.
At the end of the editing period of the dictionary, approved relations are automatically exported by
rdd into a L
X file, which are then included in a modular L
X dictionary template. The dictionary
template is language independent and renders entries produced by Ve
rdd using predefined commands as
a part of the template, which yields a full print-ready dictionary that is automatically generated. Editors
can manually check and polish the entries to ensure that the document satisfies the editorial requirements
set for publishing the dictionary.
3 Catering to the Language Community
Interaction with members of the language community in charge of editing the dictionary has been an
important part of the project since its beginning. In this section, we describe the needs that were identified
when discussing with the community members and observing their workflow.
3.1 Initial Requirements for the System
As a part of the project of editing a new version of the Finnish-Skolt Sami dictionary, a need for an editing
system arose. Since dictionary editing for Skolt Sami has been done either with paper dictionaries in mind
or with online dictionaries in mind (c.f. (H
ainen and Rueter, 2018)), a system with a user-interface
and functionality supporting both modalities was needed.
Members of any given language community cannot be expected to have mastered language documen-
tation, nor can they be expected to posses the technical skills needed to run command line applications
for morphological analysers or edit XML-formatted dictionaries. The system should therefore provide a
graphical user interface that can be used simultaneously by multiple non-technical dictionary editors.
An abstraction of the workflow is the following: the dictionary editors go through existing lexicographic
resources imported into the system. They need to verify and correct each entry with the possibility of
adding new entries when needed. As similar words behave in similar ways, the editors need a mechanism of
filtering and sorting the words in the system based on similar vowels (assonance), consonants (consonance)
and word ending. For this purpose, Ve0rdd has an extensive searching, filtering and sorting functionality.
As editors go through the lexical entries in the system, a history of changes should be kept. Ve
includes a special administrator view that shows all the edits done in the system and their respective editors.
Edits can be reverted back for individual words or individual relations without the need of reverting
anything more than necessary.
Finally, the system should be able to output its data in meaningful formats. This means outputting the
final dictionary for printing, a CSV and XML. Some of the dictionary editors are familiar with Excel
and they have a need to see the data in a format compatible with the software. Then again, some more
technical users are interested in XML for using it for NLP.
The workflow anticipated in the XML, Akusanat and even Ve
rdd have, at times, proven to be incom-
patible with those of the actual native users. This may be the result of experience with pencil and paper
approaches to language documentation. Some of the users have been more familiar with ticking translation
pairs off in a long list (all on paper first and then on Ve
rdd). For this reason we organised sessions with
the community members to better understand their needs.
3.2 First User Session
The first session with the participating community members was organized in Inari in the Finnish Lapland.
Two native Skolt Sami speakers and one non-native Skolt Sami teacher who are to edit the dictionary
participated in the tutorial session. The purpose was to get to know better how they do dictionary editing
and more concretely what their needs are. This session revealed that several key features were lacking and
that the user interface needed more refining for a better usability.
The development language of Ve
rdd has been English and therefore the user interface was initially in
English. The community members demanded it be localized in Finnish as they are not fluent enough in
English to use the system. Another interface problem was that the community members needed a quick
visual way of seeing which words and relations they had already verified. Although the system kept track
of this already, this was made visually clearer by coloring the words and relations that had already been
verified entirely in light green.
By observing how the system was used, we quickly noticed that the editors were consulting several
different pages to get their work done. They used Akusanat
to see the full inflectional paradigms of the
Skolt Sami words. Ve
rdd initially included only a miniparadigm that highlighted only the linguistically
meaningful inflections. As the community members are no linguists, however, they felt a need to see the
entire full inflection paradigms. This feature was automatically introduced in Ve
rdd by inflecting the
words with UralicNLP. Simultaneously a feature for editing the paradigms was also introduced in case the
FSTs were producing incorrect inflectional forms.
Another website the editors consulted was Sami TermWiki
, which contains a list of terms that have
been established as the official recommendations by the S
ami Giellag
aldu institution. We collected the
Skol Sami terms from the Sami TermWiki and added them to Ve
rdd. For the words that are recommended
by S´
ami Giellag´
aldu, a link to TermWiki appears in Ve0rdd.
Two new relation types were requested by the community members. First, they needed to keep some
words in the dictionary, although they are not recommended forms, but they need to be kept for the sake
of completeness with a reference to the normative form. This relation type was introduced as alternative
form relation. Furthermore, there was a wish to link derivational forms to the word they derived from.
This was done automatically with the GiellaLT transducers in UralicNLP. We processed all the words in
the system and linked the ones that received a derivational morphological reading with a matching lemma
and part-of-speech.
3.3 Second User Session
The second user session was arranged over Skype with two language community members, a student and
the instructor of the dictionary project. In this session, it became evident that the editors had resorted to a
more traditional Finnish lexicographic approach, i.e. doing editorial work in a pencil and paper fashion.
In keeping with this tradition, the three editors had been directed to inspect lists of Skolt Sami verbs with
their Finnish translations by their instructor, head editor.
This workflow, although counter-intuitive from the tool developers’ perspective, sits well with the
editors. In fact, it is difficult to entice them to use the Ve
rdd tool directly; since the previous session only
28 entries with all relations had been approved. Needless to say, another set of printed word lists was
requested. The editors preferred a list of words on paper to individual words, one at a time. As one of the
editors described it: “When I pack my suitcase, I don’t put in one individual thing at a time, so I don’t
feel good about dealing with words on an individual basis. This, in fact, illustrates the practice where
editors want to deal with one set of words at a time, i.e. there might be a part-of-speech constraint or
even features of assonance or consonance utilized in the sorting of several words for bulk approval in a
dictionary editing system.
We recognized the alignment of linguistic and first language user intuition. While a linguistic approach
to inflection type categorization might include bulk assessment of similar assonance or consonance, the
native language speakers were also looking for word form associations. For this reason we decided there
had to be an easy way to print out a list of source-language and target-language word pairs; a structure
which could also be realized as paired words with an adjacent column of tick boxes as well a columns for
identification of the individual relation. This latter feature could then be used with feeding the results
of pencil-n-paper inspections of translation, derivation and etymology relations. This interface design
decision is meant to mimic the experience they would have when using a pencil and a paper, although by
using a flat design paradigm as opposed to a fully skeuomorphic design, as there is evidence of the former
resulting in a higher perceived usability (Spiliotopoulos et al., 2018).
A second feature requested was the ability to add relations more freely to a newly added lemma in
addition to simple translation relation. This requires exposing the features stored in the relation information
to an editable form in the user interface.
4 Future Directions and Discussion
In this paper, we have presented Ve
rdd, a dictionary editing system for Skolt Sami. Our system relies on
technologies that exist in the exact same format for multiple minority languages in the GiellaLT system.
This means that the system can readily be used with a little to no configuration just by adding a new
language code from the list of 32 languages currently supported by UralicNLP.
Currently, the system is capable of automatically generating morphological inflections, and these
inflectional forms can be edited together with the continuation lexicon information. In other words, this
can be used to fix any issues that are present in the FSTs. However, at the moment, this is a manual
endeavor. Whenever the inflectional forms are edited, the person in charge of writing the FSTs can see the
edits in the administration view of Ve
rdd and adjust the FSTs accordingly. A future solution would be
to make it possible to inspect and edit FSTs directly in the system, similarly to the system proposed by
(Lepp et al., 2019).
As a longer term goal for the system is a closer integration with the GiellaLT infrastructure and Akusanat
MediaWiki dictionary. Ve
rdd currently uses the tools and lexicographic information coming from these
systems, but any edits made in Ve
rdd do not get reflected back to the other systems. As the focus is
currently in finalizing the printed Skolt Sami dictionary, this bi-directionality has been left for the future.
The development of Ve
rdd continues in close collaboration with the Skolt Sami language community.
The immediate next step is to come into an agreement on the layout of the final paper dictionary. Currently,
rdd does support outputting the lexicographic data into a L
X template that can be edited before the
final PDF version. However, the actual final layout is to be decided.

We present our ongoing development of a synchronized XML-MediaWiki dictionary to solve the problem of XML dictionaries in the context of small Uralic languages. XML is good at representing structured data, but it does not fare well in a situation where multiple users are editing the dictionary simultaneously. Furthermore, XML is overly complicated for non-technical users due to its strict syntax that has to be maintained valid at all times. Our system solves these problems by making a synchronized editing of the same dictionary data possible both in a MediaWiki environment and XML files in an easy fashion. In addition, we describe how the dictionary knowledge in the MediaWiki-based dictionary can be enhanced by an additional Semantic Me-diaWiki layer for more effective searches in the data. In addition, an API access to the lexical information in the dictionary and morphological tools in the form of an open source Python library is presented.

We present advances in the development of a FST-based morphological analyzer and generator for Skolt Sami. Like other minority Uralic languages, Skolt Sami exhibits a rich morphology, on the one hand, and there is little golden standard material for it, on the other. This makes NLP approaches for its study difficult without a solid morphological analysis. The language is severely endangered and the work presented in this paper forms a part of a greater whole in its revitalization efforts. Furthermore, we intersperse our description with facilitation and description practices not well documented in the infrastructure. Currently, the analyzer covers over 30,000 Skolt Sami words in 148 inflectional paradigms and over 12 derivational forms.

We compare different LSTMs and transformer models in terms of their effectiveness in normalizing dialectal Finnish into the normative standard Finnish. As dialect is the common way of communication for people online in Finnish, such a normalization is a necessary step to improve the accuracy of the existing Finnish NLP tools that are tailored for norma-tive Finnish text. We work on a corpus consisting of dialectal data from 23 distinct Finnish dialect varieties. The best functioning BRNN approach lowers the initial word error rate of the corpus from 52.89 to 5.73.

In the past years the natural language processing (NLP) tools and resources for small Uralic languages have received a major uplift. The open-source Giellatekno infrastructure has served a key role in gathering these tools and resources in an open environment for researchers to use. However, the many of the crucially important NLP tools, such as FSTs and CGs require specialized tools with a learning curve. This paper presents UralicNLP, a Python library, the goal of which is to mask the actual implementation behind a Python interface. This not only lowers the threshold to use the tools provided in the Giellatekno infrastructure but also makes it easier to incorporate them as a part of research code written in Python.

A key factor influencing the effectiveness of a user interface is the usability resulting from its design, and the overall experience generated while using it, through any kind of device. The two main design trends that prevail in the field of user interface design is skeuomorphism and flat design. Skeuomorphism was used in UI design long before flat design and it is built upon the notion of metaphors and affordances. Flat design is the main design trend used in most UIs today and, unlike skeuomorphic design, it is considered as a way to explore the digital medium without trying to reproduce the appearance of the physical world. This paper investigates how users perceive the two design approaches at the level of icon design (in terms of icon recognizability, recall and effectiveness) based on series of experiments and on data collected via a Tobii eye tracker. Moreover, the paper poses the question whether users perceive an overall flat design as more aesthetically attractive or more usable than a skeuomorphic equivalent. All tested hypotheses regarding potential effect of design approach on icon recognizability, task completion time, or number of errors were rejected but users perceived flat design as more usable. The last issue considered was how users respond to functionally equivalent flat and skeuomorphic variations of websites when given specific tasks to execute. Most tested hypotheses that website design affects task completion durations, user expected and experienced difficulty, or SUS (System Usability Scale) and meCUE questionnaires scores were rejected but there was a correlation between skeuomorphic design and increased experienced difficulty, as well as design type and SUS scores but not in both websites examined.

The paper presents and evaluates various NLP tools that have been created using the open source library HFST - Helsinki Finite-State Technology and outlines the minimal extensions that this has required to a pure finite-state system. In particular, the paper describes an implementation and application of Pmatch presented by Karttunen at SFCM 2011.
This paper will provide a brief description of Skolt Sami and how it might be construed as a pluricentric language. Historical factors are identified that might contribute to a pluricentric identity: geographic location and political history; shortages of language documentation, and the establishment of a normative body for the development of a standard language. Skolt Sami is assessed in the context of Sami languages and is forwarded as one of a closely related yet distinct language group. Here the issue then becomes one of facilitating diversity even for under-documented languages. And we aptly describe opportunities in language technology that have been utilized to this end. Finally, brief insight is given for other Uralic languages with regard to pluricentric character and possibilities for language users to facilitate the maintenance of their individual language needs.
