Thus, this talk here presents the development of a methodology capable for automatically converting images into natural language (NL) text sentences using image processing-analysis methods and graphs with attributes for object recognition, and image understanding. Then it converts graph representations into NL text sentences. Moreover, it presents a methodology for transforming NL sentences into Graph representations and then into Stochastic Petri-nets (SPN) descriptions in order to offer a common model of representation of multimodal information and at the same time a way of associating “activities or changes” in image frames for events representation and interpretation. The selection of the SPN graph model is due to its capability for efficiently representing structural and functional knowledge where other models cannot. Simple illustrative examples are provided for proving the concept presented here.","PeriodicalId":259975,"journal":{"name":"Proceedings of the 6th International Conference on Natural Language Processing and Knowledge Engineering(NLPKE-2010)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131050916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To extract opinion_holder, we firstly explore Conditional Random Field(CRF) based on six features including contextual, opinionated_trigger words, POS tags, named entity, dependency and proposed sentence structure feature, and dependency is adjusted to be better helpful for containing contextual dependency information. Then we propose two novel syntactic rules with opinionated_trigger words to directly identify opinion_holder from the parse trees. The results show that the precision from CRF is much higher than that of syntactic rules, while the recall is lower than. So we combine CRF with syntactic rules used as additional three features including HolderNode, ChunkPosition and Paths for the CRF to train our model. The combination results of the system illustrate the higher recall and higher F-measure under the almost same high precision.","PeriodicalId":259975,"journal":{"name":"Proceedings of the 6th International Conference on Natural Language Processing and Knowledge Engineering(NLPKE-2010)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131450001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we investigate standard statistical language models on the Persian as an inflectional language. We propose two variations of morphological language models that rely on a morphological analyzer to manipulate the dataset before modeling. Then we discuss shortcoming of these models, and introduce a novel approach that exploits the structure of the language and produces more accurate.

The most common way to tackle this problem is to utilize a readily available sentiment lexicon such as HowNet or SentiWordNet to determine whether a word is a sentiment word. However, in practice, words existing in the lexicon sometimes can not express sentiment tendency in a certain context while other words out of the lexicon do express. To address this challenge, this paper presents an approach based on maximum-entropy classification model to identify sentiment words given an opinionated sentence. Experimental results show that our approach outperforms baseline lexicon-based methods.","PeriodicalId":259975,"journal":{"name":"Proceedings of the 6th International Conference on Natural Language Processing and Knowledge Engineering(NLPKE-2010)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133917926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper is intended to analyze the syntactic correlations of prosodic phrase in broadcasting news speech. The research results in the followings: Firstly, the C-PP, which there is a stable prosodic pattern of pitch contour within its rhythmic chunking, has a flexible syntactic structure and stable semantic expression. Secondly, we find that the syntactic structure is more complex than the prosodic structure, and some conjunction and particle more likely attached to the end of left structure or the beginning of right one and form a prosodic word. If it has just four lexical words including the conjunction or particle they form a prosodic word by itself. That is to say, it has very great flexibility in prosodic structures for conjunctions and particles.","PeriodicalId":259975,"journal":{"name":"Proceedings of the 6th International Conference on Natural Language Processing and Knowledge Engineering(NLPKE-2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122622884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The baseline system is based on object related dependency relations from parsed constituents. However, the inclusion of the topic related thematic roles present in the verb based syntactic argument structure improves the performance of the baseline system. The argument structures are extracted using VerbNet. The unsupervised hybrid approach consists of two phases; firstly, the information of Rhetorical Structure (RS) is extracted to identify the target span corresponding to the emotional expression from each sentence. Secondly, as an individual target span contains one or more topics corresponding to an emotional expression, a Heuristic Classifier (HC) is designed to identify each of the topic spans associated in the target span. The classifier uses the information of Emotion Holder (EH), Named Entities (NE) and four types of Similarity features to identify the phrase level components of the topic spans. The system achieves average recall, precision and F-score of 60.37%, 57.49% and 58.88% respectively with respect to all emotion classes on 500 annotated sentences containing single or multiple emotion topics.","PeriodicalId":259975,"journal":{"name":"Proceedings of the 6th International Conference on Natural Language Processing and Knowledge Engineering(NLPKE-2010)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129041439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach has another problem is that Relevance feedback assumes that most frequent terms in the feedback documents are useful for the retrieval. In fact, the reports of some experiments show that it does not hold in reality many expansion terms identified in traditional approaches are indeed unrelated to the query and harmful to the retrieval. In this paper, we propose to select better and more relevant documents with a clustering algorithm.
