The past decade has seen enormous growth in our knowledge of the basic functions of language processing as well as their disorders. Theoretical, behavioral and neurophysiological, as well as neuroanatomical studies have helped to advance our knowledge in the field. On the one hand, the development of different methodologies and their application to the investigation of normal and impaired langu...

Continuously discovering novel entities in news and Web data is important for Knowledge Base (KB) maintenance. One of the key challenges is to decide whether an entity mention refers to an in-KB or out-of-KB entity. We propose a principled approach that learns a novel entity classifier by modeling mention and entity representation into multiple feature spaces, including contextual, topical, lex...

An ontology describes conceptual knowledge in a specific domain. A lexical base collects a repository of words and gives independent definition of concepts. In this paper, we propose to use FCA as a tool to help constructing an ontology through an existing lexical base. We mainly address two issues. The first issue is how to select attributes to visualize the relations between lexical terms. Th...

We present IndoNet, a multilingual lexical knowledge base for Indian languages. It is a linked structure of wordnets of 18 different Indian languages, Universal Word dictionary and the Suggested Upper Merged Ontology (SUMO). We discuss various benefits of the network and challenges involved in the development. The system is encoded in Lexical Markup Framework (LMF) and we propose modifications ...

This paper is concerned with the acquisition of the lexicon. In particular, we propose a method that uses analogical reasoning to hypothesize new polysemous word senses. This method is one of a number of knowledge acquisition devices to be included in DIRC (Domain Independent Retargetable Consultan0. DIRC is a kind of intelligent, natural language-capable consultant kit that can be retargeted a...

In text, lexical cohesion is the result of chains of related words that contribute to the continuity of lexical meaning. These lexical chains are a direct result of units of text being "about the same thing," and finding text structure involves finding units of text that are about the same thing. Hence, computing the chains is useful, since they will have a correspondence to the structure of th...

Two experiments are reported examining the relationship between lexical and syntactic processing during language comprehension, combining techniques common to the on-line study of syntactic ambiguity resolution with priming techniques common to the study of lexical processing. By manipulating grammatical properties of lexical primes, we explore how lexically based knowledge is activated and gui...
