ABSTRACT Both Geographic Information Systems and Information Retrieval have been very active research fields in the last decades. Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structures and techniques
to efficiently store and retrieve documents using both the text and the geographic references contained within the text.

We present in this paper a new index structure that combines an inverted index, a spatial index, and an ontology-based structure.
This structure improves the query capabilities of other proposals. In addition, we describe the architecture of a system for
geographic information retrieval that uses this new index structure. This architecture defines a workflow for the extraction
of the geographic references in the document.

    ABSTRACT: More people than ever before have access to information with the World Wide Web; information volume and number of users both continue to expand. Traditional search methods based on keywords are not effective, resulting in large lists of documents, many of which unrelated to users’ needs. One way to improve information retrieval is to associate meaning to users’ queries by using ontologies, knowledge bases that encode a set of concepts about one domain and their relationships. Encoding a knowledge base using one single ontology is usual, but a document collection can deal with different domains, each organized into an ontology. This work presents a novel way to represent and organize knowledge, from distinct domains, using multiple ontologies that can be related. The model allows the ontologies, as well as the relationships between concepts from distinct ontologies, to be represented independently. Additionally, fuzzy set theory techniques are employed to deal with knowledge subjectivity and uncertainty. This approach to organize knowledge and an associated query expansion method are integrated into a fuzzy model for information retrieval based on multi-related ontologies. The performance of a search engine using this model is compared with another fuzzy-based approach for information retrieval, and with the Apache Lucene search engine. Experimental results show that this model improves precision and recall measures.

    ABSTRACT: In the research field of Geographic Information Systems (GIS), a cooperative effort has been undertaken by several international organizations to define standards and specifications for interoperable systems. The Web Processing Service (WPS) is one of the most recent specifications of the Open Geospatial Consortium (OGC). It is designed to standardize the way that GIS calculations are made available to the Internet. We present in this paper a WPS to perform Toponym Resolution. This service defines two geospatial operations. The first operation, getAll, returns all possible geographic descriptions with the requested name ordered by a relevance ranking. The second operation, getMostProbable, filters the result and returns only the most probable geographic description. Furthermore, both operations can be parameterized according to the level of detail needed in the result.

    ABSTRACT: Many public organizations are working on the construction of spatial data infrastructures (SDI) that will enable them to share their geographic information. However, not only geographic data are managed in these SDIs, and, in general, in Geographic Information Systems (GIS), but also many textual documents must be stored and retrieved (such as urban planning permissions and administrative les). Textual index structures must be integrated with GIS in order to provide an ecient access to these documents. Furthermore, many of these documents include geographic references within their texts. Therefore, queries with geographic scopes should be correctly an- swered by the index structure and the special characteristics of these geographic references, due to their spatial nature, should be taken into account. We present in this paper a workow process that allows a gradual and collaborative creation of a document repository. These documents can be eciently retrieved using queries regarding their texts and regarding the geographic references included within them. Moreover, the index structure and the supported query types are briey described.
