Commonsense knowledge about object properties, human behavior and general concepts is crucial for robust AI applications. However, automatic acquisition of this knowledge is challenging because of sparseness and bias in online sources. This paper presents Quasimodo, a methodology and tool suite for distilling commonsense properties from non-standar...

A view with a binding pattern is a parameterized query on a database. Such views are used, e.g., to model Web services. To answer a query on such views, the views have to be orchestrated together in execution plans. We show how queries can be rewritten into equivalent execution plans, which are guaranteed to deliver the same results as the query on...

Quasimodo is an open-source commonsense knowledge base that significantly advanced the state of salient commonsense knowledge base construction. It introduced a pipeline that gathers, normalizes, validates and scores statements coming from query log and question answering forums. In this demonstration, we present a companion web portal which allows...

Formal languages are widely studied, taught and used in computer science. However, only a small part of this domain is brought to a broader audience, and students often have no practical experience in their curriculum. In this tool paper, we introduce Pyformlang, a practical and pedagogical Python library for formal languages. Our library implement...

Commonsense knowledge (CSK) about concepts and their properties is useful for AI applications. Prior works like ConceptNet, COMET and others compiled large CSK collections, but are restricted in their expressiveness to subject-predicate-object (SPO) triples with simple concepts for S and strings for P and O. This paper presents a method, called ASC...
Chapter

A view with a binding pattern is a parameterised query on a database. Such views are used, e.g., to model Web services. To answer a query on such views, one has to orchestrate the views together in execution plans. The goal is usually to find equivalent rewritings, which deliver precisely the same results as the query on all databases. However, suc...
Conference Paper
Full-text available
In this system demonstration, we study views with binding patterns, which are a formalization of REST Web services. Such views are database queries that can be evaluated using the service, but only if values for the input variables are provided. We investigate how to use such views to answer a complex user query, by rewriting it as an execution pla...

Thesis
Full-text available
In this thesis, we harvest knowledge of two different types from online resources. The first one is commonsense knowledge, i.e. intuitive knowledge shared by most people like "the sky is blue". We extract salient statements from query logs and question-answering sites by carefully designing question patterns. Next, we validate our statements by que...
