This paper focuses on the trade-off between the deduplication rate and the processing penalty in backup system which uses a conventional variable chunking method. The trade-off is a nonlinear negative correlation if the chunk size is fixed. In order to analyze quantitatively the trade-off all over the factors, a simulation approach is taken and clarifies the several correlations among chunk siz...

In this paper we describe our system (DTSim) submitted at SemEval-2016 Task 2: Interpretable Semantic Textual Similarity (iSTS). We participated in both gold chunks category (texts chunked by human experts and provided by the task organizers) and system chunks category (participants had to automatically chunk the input texts). We developed a Conditional Random Fields based chunker and applied r...

In this paper, a method for the word alignment of English-Chinese corpus based on chunks is proposed. The chunks of English sentences are identified firstly. Then the chunk boundaries of Chinese sentences are predicted by the translations of English chunks and heuristic information. The ambiguities of Chinese chunk boundaries are resolved by the coterminous words in English chunks. With the chu...

We report on chunk tagging methods for German that recognize complex non-verbal phrases using structural chunk tags with Conditional Random Fields (CRFs). This state-of-the-art method for sequence classification achieves 93.5% accuracy on newspaper text. For the same task, a classical trigram tagger approach based on Hidden Markov Models reaches a baseline of 88.1%. CRFs allow for a clean and p...

Disk-based backup storage system is utilized widely, and data deduplication is becoming an essential technique in the system because of the advantage of a spaceefficiency. Usually, user’s several files are aggregated into a single Tar file at primary storage, and the Tar file is transferred and stored to the backup storage system periodically (e.g., a weekly full backup) [1]. In this paper, we ...

This paper describes an alternative translation model based on a text chunk under the framework of statistical machine translation. The translation model suggested here first performs chunking. Then, each word in a chunk is translated. Finally, translated chunks are reordered. Under this scenario of translation modeling, we have experimented on a broadcoverage Japanese-English traveling corpus ...

Chunk scheduling is one of the key components in P2P streaming systems. Most of previous research works focus on receiver side’s chunk/peer selection strategies and neglect the service order and available uplink bandwidth allocation problem at supplier side, which will cause the user’s video quality descending under overloaded operating environments. In this paper, we propose the supplier side ...

We present a noun chunker for German which is based on a head-lexicalised probabilistic contextfree grammar. A manually developed grammar was semi-automatically extended with robustness rules in order to allow parsing of unrestricted text. The model parameters were learned from unlabelled training data by a probabilistic context-free parser. For extracting noun chunks, the parser generates all ...

Functional elements (determiners, complementizers, modals, degree words) are in many ways the syntactic analogues of affixes in morphology. Typically, functional elements are bound elements. Phonologically, they are clitics: syntactically, they are unable to appear without an associated thematic element (noun, verb, adjective). I would like to extend the analogy by showing that functional eleme...
