By appearance of social media, people are coming to be able to transmit information easily on a personal level. However, because users of social media generally spend little time on describing information, low-quality texts are transmitted and it blocks the spread of information. On transmitted texts in social media, commas and linefeeds are inserted incorrectly, and it becomes a factor of low-...

Current ILP algorithms typically use variants and extensions of the greedy search. This prevents them to detect signiicant relationships between the training objects. Instead of myopic impurity functions, we propose the use of the heuristic based on RELIEF for guidance of ILP algorithms. At each step, in our ILP-R system, this heuristic is used to determine a beam of candidate literals. The bea...

Most implementations of AND-parallelism tackle the shared variable problem by running literals in parallel only if they have no variables in common and thus are independent from each other. But even in its independent form, AND-parallel clause execution remains an intricate matter with numerous problems to be solved. First to mention, a carefully worked out synchronization mechanism is required...

We present a formalism that models the computation of clause sharing portfolio solvers with inprocessing. The soundness of these solvers is not a straightforward property since shared clauses can make a formula unsatisfiable. Therefore, we develop characterizations of simplification techniques and suggest various settings how clause sharing and inprocessing can be combined. Our formalization mo...

This paper presents a parse-and-paraphrase paradigm to assess the degrees of sentiment for product reviews. Sentiment identification has been well studied; however, most previous work provides binary polarities only (positive and negative), and the polarity of sentiment is simply reversed when a negation is detected. The extraction of lexical features such as unigram/bigram also complicates the...

This paper describes and evaluates the automatic annotation of clause-level complements with semantic roles in a Spanish Web corpus, using a ruleand dependency-based approach. In all, 52 different role tags, like agent (§AG), experiencer (§EXP), location (§LOC) etc. are distinguished. The annotator uses a role grammar of 568 hand-written Constraint Grammar rules that take as input the syntactic...

We describe an N-gram based syntactic analysis using a dependency grammar. Instead of generalizing syntactic rules, N-gram information of parts of speech is used to segment a sequence of words into two clauses. A special part of speech, called segmentation word, which corresponds to the beginning or end symbol of clauses is introduced to express a sentence structure. Segmentation words for each...

In the current work, we test the hypothesis that 'at-issue' and 'not-at-issue' content (Potts, 2005) are processed semi-independently. In a written rating study comparing restrictive relative clauses and parentheticals in interrogatives and declaratives, we observe a significantly larger length penalty for restrictive relative clauses than for parentheticals. This difference cannot be attribute...
