Detecting "protein words" through unsupervised word segmentation

Unsupervised word segmentation methods were applied to analyze the protein sequence. Protein sequences, such as 'MTMDKSELVQKA...', were used as input to these methods. Segmented 'protein word' sequences, such as 'MTM DKSE LVQKA', were then obtained. We compare the 'protein words' produced by unsupervised segmentation and the protein secondary structure segmentation. An interesting finding is that the unsupervised word segmentation is more efficient than secondary structure segmentation in expressing information. Our experiment also suggests there may be some 'protein ruins' in current noncoding regions.

A new DNA alignment method based on inverted index

This paper presents a novel DNA sequences alignment method based on inverted index. Now most large scale information retrieval system are all use inverted index as the basic data structure. But its application in DNA sequence alignment is still not found. This paper just discuss such applications. Three main problems, DNA segmenting, long DNA query search, DNA search ranking algorithm and evaluation method are detailed respectively. This research presents a new avenue to build more effective DNA alignment methods.
