INTRODUCTION "Research" in design has a long but not very robust history. Individuals have published on the subject almost from the time design was recognized as something to be taught (engineering and architectural design theories have been in the literature since Roman times). Yet, despite exceptional efforts by some individuals, the degree of interest in research among the design disciplines...

This paper introduces GKB, a repository based on a domain-independent meta-model for integrating geographic knowledge collected from multiple sources. We present the architecture, the repository design and the data cleaning and knowledge integration processes. We also describe the rules developed to add new knowledge to the repository. GKB includes tools for generating ontologies, which are bei...

The Streaming Slot Filler (SSF) task in TREC Knowledge Base Acceleration track involves detecting changes to slot values (relations) over time. To handle this task, the system needs to extract relations to identify slot-filler values and detect novel values. Being the first attempt at KBA, the biggest challenge that we faced was the scale of the data. We present the approach used by University ...

The Knowledge Base Discovery Tool (KBDT) is a suite of tools and components to improve the indexing of and search for documents. KBDT extracts and displays content from documents and builds knowledge indexes based on meaning, rather than keywords. KBDT uses the indexes to perform more intelligent searches. It also includes visualization technology to display relevant results using multi-media, ...

Given two versions of a knowledge base (KB), independently modified, we investigated the problem of incorporating changes made to one KB version into the other. We have implemented a system that will perform such a reintegration, autonomously, using predetermined user preferences. This effort has lead to a greater insight into the version reintegration problem and has highlighted those areas wh...

We present syntactic characterizations of propositional update operators based in the PMA approach Winslett, 1988a, Winslett, 1988b]), and develop algorithms for computing the updated database on the basis of this characterization. Unlike any other previous work in this area, the methods presented here do not require direct manipulation or explicit storage of complete models of the database. Th...

Intelligent text-oriented tools for representing and searching the biological research literature are being developed, which combine object-oriented databases with artificial intelligence techniques to create a richly structured knowledge based of Materials and Methods sections of biological research papers. A knowledge model of experimental processes, biological and chemical substances, and an...

Much attention has recently been given to the creation of large knowledge bases that contain millions of facts about people, things, and places in the world. These knowledge bases have proven to be incredibly useful for enriching search results, answering factoid questions, and training semantic parsers and relation extractors. The way the knowledge base is actually used in these systems, howev...

The present communication aims to report the TAC forum about the system-incorporated towards Entity-Linking task. The noun-phrases relevant to the search term were used to correlate the entityrelevant happenings mentioned in the source documents to that of the entity-relevant information in the knowledge-base. Care was taken in identifying the abbreviation and full form variants of search names...
