In this paper we define a similarity measure between semantic valence frames. It is based on a similarity measure between senses of verb arguments. Senses are represented by general semantic categories or wordnet synset. The measure is supposed to be used for aggregation of semantic valence frames that differ in NP/PP slot senses but represent the same meaning of the verb.

In this paper, we propose to build temporal ontologies from WordNet. The underlying idea is that each synset is augmented with its temporal connotation. For that purpose, temporal classifiers are iteratively learned from an initial set of time-sensitive synsets and different propagation strategies to give rise to different TempoWordNets.

YARN (Yet Another RussNet) project started in 2013 aims at creating a large open thesaurus for Russian using crowdsourcing. This paper describes synset assembly interface developed within the project — motivation behind it, design, usage scenarios, implementation details, and first experimental results.

This paper describes a first a t tempt at a statistical model for simultaneous syntactic parsing and generalized word-sense disambignation. On a new data set we have constructed for the task, while we were disappointed not to find parsing improvement over a traditional parsing model, our model achieves a recall of 84.0% and a precision of 67.3% of exact synset matches on our test corpus, where ...

Morphological processes in a language can be effectively used to enrich individual wordnets with semantic relations. More importantly, morphological processes in a language can be used to discover less explicit semantic relations in other languages. This will both improve the internal connectivity of individual wordnets and also the overlap across different wordnets. Using morphology to improve...

This work tries to enrich the Spanish Wordnet using a Spanish taxonomy as a knowledge source. The Spanish taxonomy is composed by Spanish senses, while Spanish Wordnet is composed by synsets, mostly linked to English WordNet. A set of weighted associations between Spanish words and Wordnet synsets is used for inferring associations between both taxonomies.

This paper describes an attempt to develop Punjabi WordNet by using expansion approach from Hindi WordNet under Indradhanush WordNet Project. The origin, symbols, morphological and syntactic characteristics of Punjabi Language are presented in this paper. The lexical semantic relations used in Punjabi WordNet are elaborated. The need for synset categorization and the results of this categorizat...

In this paper we propose a system for the recommendation of tagged pictures obtained from the Web. The system, driven by user feedback, executes an abductive reasoning (based on WordNet synset semantic relations) that is able to iteratively lead to new concepts which progressively represent the cognitive creative user state. Furthermore we design a selection mechanism to pick the most relevant ...

Lexically rich resources form the foundation to all NLP tasks. Maintaining the high quality of resources is thus a high priority issue. In this paper we exhibit the tools developed at IIT Bombay, for the purpose of creation, enhancement and maintenance of the WordNets, as well as the ones used for NLP tasks that use WordNets directly, like Word Sense Disambiguation. The paper presents online an...

The Japanese WordNet currently has 51,000 synsets with Japanese entries. In this paper, we discuss three methods of extending it: increasing the cover, linking it to examples in corpora and linking it to other resources (SUMO and GoiTaikei). In addition, we outline our plans to make it more useful by adding Japanese definition sentences to each synset. Finally, we discuss how releasing the corp...
