[Article Title: On the Effective use of Image-Based Feedback: Developing an Intelligent Tutoring System for Japanese Language Particles/ Zachary T. Chung, Hiroko Nagai, and Ma. Mercedes T. Rodrigo, p. 1-7]

Abstract: In recent years, an increasing number of Ateneo de Manila University students have been taking an interest in the Japanese language. For these students beginning their study of the language however, Japanese particles are difficult concepts because they cannot be translated to equivalent words in English. For a beginner learner, it is inevitable to view a second language with the lens of a first language as shown by the concept of transfer in second language acquisition. As a result, learners tend to misconstrue Japanese particles by attempting to understand them with respect to non-existent equivalents in English. In this research, we develop an intelligent tutoring system for Ateneo de Manila University students taking introductory Japanese to aid them better understand Japanese particles. The system assesses the learner's understanding of Japanese particles by practice and depending on which particle where most mistakes are made, the system would give instructional feedback. Feedback to be implemented in the system use visual prototypes that represent the meaning of the particle. We hope to see if visual representations can also teach Japanese particles to students as an alternative to text-detailed explanations such as those commonly found in textbooks.

[Article Title: On the Translations of an Autograph/ Lauro L. Fontanil and Rolando G. Panopio, p. 8-11]

Abstract: A graph G is an autograph if its vertices can be labeled bijectively by a multiset S of numbers called signature such that two vertices are adjacent if and only if the absolute difference of the corresponding labels is also in S. Given a signature S and its corresponding autograph G (S), the autograph with signature whose elements resulted from adding a fixed real number to every element of S is called a translation of G (S). In this study, properties of translations of autographs were determined. These include the number of edges a translation consists and some necessary conditions for two translations to be isomorphic. The exact number of nonempty translations of an autograph with signature consisting of integers was also found. This result is a refinement of the previous one which only gives bounds on the number of nonempty translations an autograph could have.

[Article Title: Correctness and Algorithmic Efficiency of a Method for Systems Genetics/ Jan Michael Yap, Henry Adorna, Ramil Mauleon and Eduardo Mendoza, p. 12-18]

Abstract :In systems biology and genetics, data integration is a key task towards providing a multi-perspective analysis of biological phenomenon. To validate algorithms developed for such purposes, empirical testing is usually done. Theoretical analysis of the algorithm would further highlight properties of a method. In this paper, a method for integrating genetic marker, quantitative trait loci (QTL), phenotypic, and gene sequence data to identify candidate genes causal to a trait is analyzed for algorithmic effectivity and efficiency. Results of the analysis prove the correctness of the method. Addition-ally, the results show that the method has time complexity O(ng(m+g)), while the space complexity is O(n(m+g+q)),where n is the number of individuals, g is the number of genes, m is the number of markers used as input, and qis the number of quantitative trait loci associated with the trait.

[Article Title: Extracting Keywords from Meeting Documents/ Caslon Chua, p. 19-23]

Abstract: Information plays an important role for management to make sound decision in an organization. As organization keeps documents in electronic format, it appears that aside from the possible, well-organised folders in a disk and well-meaning filenames given to documents, searching documents based on contents is difficult. In addition, most if not all document search requires the user to recall exact phrases in the document for search and retrieval. In an organization where administrators changes over time, decisions, recommendations, suggestions and other important things that were recorded formally in a document may remain unknown to new administrators. New administrators may have to exert pro-active efforts to retrieve previous decisions before making a new one, due to possible contradiction or repetition. As the volume of document increases, search and retrieval become tedious and difficult. This study presented an approach to parse and analyse meeting documents to extract keywords in preparation for indexing and clustering.
