creativeness / a pleasing field / of bloom Word associations are an important element of linguistic creativity. Traditional lexical knowledge bases such as WordNet formalize a limited set of systematic relations among words, such as synonymy, polysemy and hy-pernymy. Such relations maintain their sys-tematicity when composed into lexical chains. We claim(More)
We present a new method to evaluate a search ontology, which relies on mapping ontology instances to textual documents. On the basis of this mapping, we evaluate the adequacy of ontology relations by measuring their classification potential over the textual documents. This data-driven method provides concrete feedback to ontology main-tainers and a(More)
We present an authoring system for logical forms encoded as conceptual graphs (CG). The system belongs to the family of WYSIWYM (What You See Is What You Mean) text generation systems: logical forms are entered interactively and the corresponding linguistic realization of the expressions is generated in several languages. The system maintains a model of the(More)
Computational linguistics methods are typically first developed and tested in English. When applied to other languages, assumptions from English data are often applied to the target language. One of the most common such assumptions is that a " standard " part-of-speech (POS) tagset can be used across languages with only slight variations. We discuss in this(More)
This paper presents the integration of a large-scale, reusable lexicon for generation with the FUF/SURGE unification-based syntactic realizer. The lexicon was combined from multiple existing resources in a semi-automatic process. The integration is a multi-step unification process. This integration allows the reuse of lexical, syntactic, and semantic(More)
Hebrew includes a very productive noun-compounding construction called smixut. Because smixut is marked morphologically and is restricted by many syntactic constraints, it has been the focus of many descriptive studies in Hebrew grammar. We present the treatment of smixut in HUGG, a FUF-based syntactic realization system capable of producing complex noun(More)
We report on an effort to build a corpus of Modern Hebrew tagged with parts of speech and morphology. We designed a tagset specific to Hebrew while focusing on four aspects: the tagset should be consistent with common linguistic knowledge; there should be maximal agreement among taggers as to the tags assigned to maintain consistency; the tagset should be(More)
Information Retrieval (IR) research has recently started addressing the information need of exploratory search. where the searcher may be unfamiliar with the domain or not have decided what is the goal of his query. A popular tool to support exploratory search is the use of faceted search. The implementation of faceted search requires that documents be(More)
Natural language generation (NLG) refers to the process of producing text in a spoken language, starting from an internal knowledge representation structure. Aug-mentative and Alternative Communication (AAC) deals with the development of devices and tools to enable basic conversation for language-impaired people. We present an applied prototype of an(More)
