  • Use of Sound Symbolism in Sentiment Classification

    Language:English   Publisher:The Association for Natural Language Processing  

    In linguistics, sound symbolism is an idea that the vocal sounds of certain words carry meaning in themselves. This paper focuses on the sound symbolism of onomatopoeic words and demonstrates the close relationship between sound symbolism and sentiment polarity. Because onomatopoeic words imitate the sounds they represent, they can help us better understand the sentiment of a sentence when utilizing sound symbolism. Therefore, we modeled sound symbolism with N-gram-based features and applied the model to a series of sentiment classification tasks. The experimental results show that this method with sound symbolism significantly outperformed the baseline method without sound symbolism, which effectively demonstrates that a close relationship exists between sound symbolism and sentiment polarity.

  • Collecting Object-attribute Noun Pairs and Constructing Concept Graphs for the Argument of Adjectives from Japanese N1-Adj-N2 Constructions

     More details

    Language:English   Publisher:Information and Media Technologies Editorial Board  

    In this paper, we propose a method for exploring the Japanese construction N1-Adj-N2, which often establishes a relationship between an object (N2), an attribute (N1), and an evaluation of that attribute (Adj). As this construction connects two nouns, our method involves constructing a graph of the noun relations, which can be considered as representing selectional restrictions for the argument of a target adjective. The exploration of N1-Adj-N2 constructions is useful for opinion mining, lexicographical analysis of adjectives, and writing aid, among others.

    Some social media users do not link their accounts on other social media platforms. However, the user identity is sometimes revealed by others due to the characteristics of expressions and topics in the posts. In this paper, we first examine what kinds of characteristics can be a clue for user identification by constructing a system for identifying user accounts on Twitter and blogs, and then propose a system to prevent identification of user accounts on different social media platforms on the basis of the findings from the user identification system.

    Events, festivals or product releases are often announced via microblogs such as Twitter. Many users post messages that are relevant to the announcements. Such relevant posts are useful for both the authors of the announcements and the users who are interested in public opinions to the announcements. However, it is not easy to collect such relevant posts because many of the relevant posts are not explicitly associated with the announcement post. In this paper, we propose a method for efficiently collecting such posts that are only implicitly relevant posts to announcements, focusing on retweets of Twitter in particular.

    Due to the development of web services, internet users are given a lot of opportunities to upload text to the internet. As a consequence, we can see many new katakana words such as "パフェる(pafe-ru)" and "リムる(rimu-ru)." However, it is sometimes hard to understand their meanings at a glance. Since paraphrases and etymologies can be a good clue to understand their meanings, we propose a method that acquires paraphrase and etymology of katakana verbs with using statistical distribution of case elements.

    In recent years, micloblogs have appeared and become prevalent all over the world. Since the characteristics of the information contained in micloblogs are considered to be different from those contained in conventional media, we can get a lot of useful information from micloblogs. However, commonly used topic models, such as LDA, do not work well on micloblogs, since these topic models do not take into account the relationships between adjacent posts and the shortness of each post. In this paper, we propose a new topic model for micloblogs that takes into account the relationships between adjacent posts.

    We propose a method for opinion summarization of product reviews. Our method generates a summary by identifying evaluative expressions in the reviews on a product, and selecting representative ones from the identified expressions. As evaluative expressions, we focus on pairs of an aspect and its evaluation, which are identified out of dependency parse trees. We employ the facility location summarization model to select representative aspect-evaluation pairs.

    Screen readers play an important role when visually impaired people access the information using a computer. A screen reader is a software that produces voice output of text on a computer screen. Some screen readers have functions of producing voice output of distinctive explanations for kanji. There are a lot of kanji characters that have the same pronunciation, and the role of distinctive explanation is to enable users to identify a unique kanji character only by listening to the explanation. For example, "購" (kou) can be identified by a distinctive explanation "kou-nyu no kou" (kou for kou-nyu). On the other hand, it is difficult to identify a unique kanji "購" by a distinctive explanation "kou-bai no kou" (kou for kou-bai), because there are multiple words with the reading "koubai", such as "勾配", "公売" and "購買" Such confusing explanations for kanji are sometimes produced by the existing screen readers. In this study, we propose a corpus-based method for automatic generation of distinctive explanations for kanji, in which information about intimacy and homophone of kanji is taken into consideration.

    In this paper, we intend to extract tuples of evaluative expression on targets from web texts. An evaluative tuple contains three types of elements, target, attribute and evaluation. We expand the scope of elements to continuous words instead of a single word to collect more diverse types of expressions. We propose a new method to learn to extract tuples taking into account dependency within expressions, because the target and attribute have a high correlation with evaluation each other. We will discuss an issue and resolution based on the results of experiments on the tagged web texts corpus.

    Many people are often faced with the situation where they need to use their cellular phones to browse web pages. However, since web pages are usually designed for computers, people often find it hard to browse web pages with a cellular phone. We focus our attention on images. Images should thus be resized to a smaller size or replaced with text metadata depending on the kinds of the images. Therefore, we first classify images into categories according to their functions in the web pages, and generate text metadata for the images depending on their category. We then use them to generate web pages which can be easily browsed with a cellular phone.

    Local coherence, which captures text relevance at the level of sentence-to-sentence transitions, is used for evaluation of text quality. For entity grid model focusing on transitions of syntactic role of entity between sentences, we investigate the effectiveness of features such as conjunction, coreference, syntactic role expansion and entity abstraction using Nihongo-Goi-Taikei. Through experiments of the sentence ordering task and the comparing summaries based on subjective assessment, we show that these features contribute to improve the performance of entity grid model.

    Personal names are often submitted to search engines as query keywords. However, in response to a personal name query, search engines return a long list of search results that contains Web pages about several namesakes. In order to address this problem, most of the previous works that disambiguate personal names in Web search results often employ agglomerative clustering approaches. In contrast, we have adopted a semi-supervised clustering approach to integrate similar documents into a seed document. Our proposed semi-supervised clustering approach is novel in that it controls the fluctuation of the centroid of a cluster.

    We propose a method of domain adaptation for sentiment classification. In this task, we are to learn a sentiment classifier on the condition that we have access to a relatively large training dataset from the source domain, but only a small training dataset from the target domain. We propose the weighted maximum entropy model for this task. This model is obtained by maximlzing the weighted log-likelihood and can be regarded as a classifier trained undef covariate shift. We also propose a method for calculating the weight on each instance with the calibrated probability of word unigram model. Through experiments of sentiment classification, we empirically show that the proposed method makes use of training instances from the source domain and improves the classification accuracy of sentiment classification.

    Classifying blogs, e.g. identifying bloggers' gender or age, is one of the most interesting problems in blog analysis today. Although it is usually solved by applying supervised learning techniques, it is not always easy to collect labeled blogs enough to train an accurate classifier. To the contrary, we can collect a huge amount of blogs that have no labels. In this paper, therefore, we propose a semi-supervised learning method for blog classification in order to incorporate unlabeled data into supervised learning. We assume that the entries from the same blog have the same characteristics. With this assumption, our method captures the characteristics of each blog, such as writing styles, and uses it to improve classification accuracy.

    We discuss text summarization in terms of maximum coverage problem and its variant. To solve the optimization problem, we applied some decoding algorithms including the ones never used in this summarization formulation, such as a greedy algorithm with performance guarantee, a randomized algorithm, and a branch-and-bound method. We conduct comparative experiments. On the basis of the experimental results, we also augment the summarization model so that it takes into account the relevance to the document cluster. Through experiments, we showed that the augmented model is at least comparable to the best-performing method of DUC'04.

    In this paper, we propose a machine learning method that uses word-level semantic orientations for sentiment classification of sentences. The simplest solution to this problem would be the majority voting by the number of positive words and the number of negative words in the given sentence. However, the semantic orientations of words in a sentence are not always the same as that of the sentence, because there can be polarity-shifters such as negation expressions. This inconsistency of word-level orientation and sentence-level orientation often causes errors in classification by the simple majority voting method. The machine learning method that we propose in this paper models the polarity-shifters. Our model can be trained in two different levels:word level and sentence level. While the word-level training focuses on the prediction of polarity shifts, the sentence-level training focuses more on the prediction of sentence orientations. The model can also combined with features used in previous work such as bag-of-words and dependency trees. We report that the proposed method improves the accuracy of sentence classification by up to 4.2 points compared with other simpler methods.

    In this paper, we propose a machine learning method that uses word-level semantic orientations for sentiment classification of sentences. The simplest solution to this problem would be the majority voting by the number of positive words and the number of negative words in the given sentence. However, the semantic orientations of words in a sentence are not always the same as that of the sentence, because there can be polarity-shifters such as negation expressions. This inconsistency of word-level orientation and sentence-level orientation often causes errors in classification by the simple majority voting method. The machine learning method that we propose in this paper models the polarity-shifters. Our model can be trained in two different levelsrword level and sentence level. While the word-level training focuses on the prediction of polarity shifts, the sentence-level training focuses more on the prediction of sentence orientations. The model can also combined with features used in previous work such as bag-of-words and dependency trees. We report that the proposed method improves the accuracy of sentence classification by up to 4.2 points compared with other simpler methods.

    We propose a machine learning-based method for identifying when an event in blog text occurs : , morning, daytime, evening, night. Earlier study analyzed explicit temporal expressions of events and mapped them on time-line in newswire texts. However, other texts such as weblogs contain few explicit temporal expressions. We therefore use various implicit temporal expressions extracted automatically. Specifically, we use naive bayes classifiers backed up with the EM algorithm, and also use support vector machines.

    We propose a model for phrases with semantic orientations as well as a classification method based on the model. Although each phrase consists of multiple words, the semantic orientation of the phrase is not a mere sum of the orientations of the component words. Some words invert the orientation. In order to capture the property of such phrases, we introduce latent variables into the model. Through experiments, we show that the proposed latent variable model works well in the classification of semantic orientations of phrases and achieved nearly 82% classification accuracy.

    Patent specifications consist of patent claims and detailed descriptions.While patent claims are the most important part of patent specifications, they are compositionally or combinationally described and difficult to read.By aligning patent claims with the "detailed description", (1) the functions and the effects of the claim can be clarified, (2) the important elements in the claims can be identified, or (3) paraphrases for the expressions in the claim can be obtained.In this paper, we propose a method to align patent claims with the "detailed description" by analyzing the structure of claims to get core elements of claims and by doing local alignments starting from word blocks including declinable words.By using 88 patent specifications out of 100 which were randomly picked up from the NTCIR3 patent data collection, the effectiveness of the method is demonstrated.

    In this paper, we propose a new method of analyzing Japanese relative clauses. Japanese relative clause modification should be classified into at least two major semantic categories : case-slot gapping and head restrictive. In previous methods, only the information for judging a clause to be such as case-frames, and cooccurrence information between nouns and verbs is taken into account. Our proposed method also takes into account the information for head restrictive. In the result of experiments, we could yield higher accuracy than previous methods of using case-frames. Moreover we got high...

  • Evaluation of Summaries Based on Lexical Chains Using Information Retrieval Task

    The importance of the automatic summarization research is now increasing with the growing availability of on-line documents. In information retrieval systems, summaries can be used as the display of the retrieval results, in order for users to quickly and accurately judge the relevance of the documents which are returned as a result of the users'query. Here, rather than producing a generic summary, the summary that reflects the user's topic of interest expressed in the query would be considered as more suitable. This type of summary is often called'query-biased summary'. In this paper, we show that our previously proposed passage extraction method based on lexical chains can be used to produce better query-biased summaries for information retrieval systems. To evaluate the effectiveness of our method, a task-based evaluation scheme is adopted. The results from the experiments support that querybiased summaries by lexical chains outperform others in the accuracy of subject's relevance judgments. Furthermore, to establish a better evaluation methodology, we also investigate and describe the problems that arise from the experimental design.

    We present a new parsing mehtod using ID/LP rules directly without transforming them to context-free grammar rules. The mehtod regards aprsing as traversal of the generalized discrimination networks and represents the parsing states as nodes in the networks. This can yield more compact representation of the parser's state sets compared with previous methods and hence more wasteful computations can be avoided. We also optimize LP rules checking so that it can be checked efficiently. Our parsing strategy is a variant of the chart method which is customized to match ID/LP rules. Using this strategy, a large amount of overhead in processing can be omitted. Comparisons of our method with other related works are also described.

    本研究交流は、高齢者が他者と会話などをしている状況において、明示的な検索要求なしで会話の文脈などの情報を利用することで、思い出せない過去の経験などについての情報想起を支援するシステムを研究開発することを目的とする。 具体的には、1) 個人の経験を示す文書、写真、ビデオなどのデータを収集し、2) それらに様々な情報を付与することで、個人の知識ベースを構築した上で、3) 個人知識ベースを知的に検索し、4) 検索した情報を提示するシステムを研究開発する。日本側チームはすでに2)、 4)で多くの成果を上げており、台湾側チームは2)、3)に強みを持っており、それぞれの強みのある部分を中心に研究開発を行う。 日台の研究チームによる共同研究を通して、高齢者が幸福かつ健康に暮らす上で重要な、他者とのコミュニケーションを促進する情報想起支援システムが実現し、文化や伝統の継承がより円滑に進められると期待される。

    本研究交流は、1)評価・感情分析技術の研究開発、特に、評価・感情の持ち主同定、話題検出、語/句/文/文書レベルでの評価分類に関する研究開発、2)心理学領域における応用開発、特に、精神医学的分析のための計算モデルの研究開発、などを目的とする。 具体的には、評価・感情分析のために必要な評価表現辞書の構築は双方が共同で行い、言語独立なアルゴリズム開発を目指すが、主に日本側は日本語に関する研究、インド側はベンガル語に関する研究を担当する。 本研究交流で日本-インド間の交流を通じて相互的に取り組むことで、多言語の評価・感情分析技術を開発するとともに、日本、インド両国における評価・感情分析研究の活発化につながることが期待される。
