In this article, we study the conditions under which having ties that span organizational boundaries (bridging ties) are conducive to the generation of innovations. Whereas previous research has shown that bridging ties have a positive impact on innovative performance, our analysis of 276 R&D scientists and engineers reveals that there are no advantages associated with bridging per se. In contr...

This paper describes a coreference resolution system for math problem text. Case frame dictionaries and a math taxonomy are utilized for supplying domain knowledge. The system deals with various anaphoric phenomena beyond wellstudied entity coreferences.

We describe a method for determining the names of RFID-tagged objects in activity videos using descriptions which have been parsed to provide anaphoric reference resolution and ontological categorization.

This paper presents two approaches to Portuguese anaphor resolution, one based on a morpho-syntactic information and other on semantic features. We present a corpus based evaluation, focusing especially on anaphoric definite descriptions, which includes direct, indirect and associative anaphors.

This article examines the anaphoric status of do so anaphora, reclassifying it as deep anaphora in Hankamer and Sag’s (1976) dichotomy of deep versus surface anaphora. Originally considered surface anaphora, do so has been shown to exhibit mixed behavior when the full range of empirical facts are considered. I look at data from a wide variety of diagnostics and show that do so’s behavior as sur...

In this paper we analyse anaphoric pronouns in control sentences and we investigate the implications of these kinds of sentences in relation to the Propositional Theory versus Property Theory question. For these purposes, we invoke the categorial calculus with limited contraction, a conservative extension of Lambek calculus that builds contraction into the logical rules for a customized slash t...

Natural Language Engineering tasks require large and complex annotated datasets to build more advanced models of language. Corpora are typically annotated by several experts to create a gold standard; however, there are now compelling reasons to use a non-expert crowd to annotate text, driven by cost, speed and scalability. Phrase Detectives Corpus 1.0 is an anaphorically-annotated corpus of en...

In the paper we describe the method of encoding communication of agents in a multi-agent system (MAS). The autonomous agents communicate with each other by exchanging messages formulated in a near-to-natural language. Transparent Intensional Logic (TIL) is an expressive system primarily designed for the logical analysis of natural language; thus we make use of TIL as a tool for encoding the sem...

Centrality – Refers to the number of ties one has to others in a network. Those with more ties may have more access to resources contained within the network. Closure – Refers to the interconnections members have with one another, that is, the social ties among the network members that are historical and bridging. Density – Refers to the number and strength of ties among individuals within a so...
