Sentence-level aligned parallel texts are important resources for a number of natural language processing (NLP) tasks and applications such as statistical machine translation and cross-language information retrieval. With the rapid growth of online parallel texts, efficient and robust sentence alignment algorithms become increasingly important. In this paper, we propose a fast and robust sentence alignment algorithm, i.e., Fast- Champollion, which employs a combination of both length-based and lexiconbased algorithm. By optimizing the process of splitting the input bilingual texts into small fragments for alignment, Fast- Champollion, as our extensive experiments show, is 4.0 to 5.1 times as fast as the current baseline methods such as Champollion (Ma, 2006) on short texts and achieves about 39.4 times as fast on long texts, and Fast-Champollion is as robust as Champollion.

The primary aim of identifying the binding motifs in gene regulation is to understand the transcriptional regulation molecular mechanism systematically. In this study, the (, d) motif search issue was considered which entails finding the length motifs which differ by at most d substitutions. However, identifying the high-quality pattern (, d) is challenging. It is intended to address the above problem with motif discovery and handle it using the proposed algorithm S2F (Segmentation to Filtration) based on the qPMS (quorum Planted Motif Search) algorithm model. From the entire DNA sequences, five percent are chosen at random to be used in the motif discovery process. This random sub segment (subseg) portion is split up into base, sub k-mers, and its sizes (motif length ()) are determined by the iterative approach. Corresponding to the sizes of and d (mutations), the k-mers are chosen which participated in filtration techniques and the base k-mer count and frequency are updated. The highest frequency of k-mer is recognized as the motif. The algorithm’s performance was evaluated using the two real datasets Escherichia coli cyclic AMP receptor protein (CRP) and mouse Embryonic Stem Cell (mESC) ChIP-seq (Chromatin Immuno Precipitation) dataset. Results from the experiments show that S2F can identify the motifs and appear faster compared to previous state-of-the-art PMS (Planted Motif Search) and qPMS algorithms.

This paper studies the problem of selecting queries to efficiently crawl a deep web data source using a set of sample documents. Crawling deep web is the process of collecting data from search interfaces by issuing queries. One of the major challenges in crawling deep web is the selection of the queries so that most of the data can be retrieved at a low cost. We propose to learn a set of queries from a sample of the data source. To verify that the queries selected from a sample also produce a good result for the entire data source, we carried out a set of experiments on large corpora including Gov2, newsgroups, wikipedia and Reuters. We show that our sampling-based method is effective by empirically proving that 1) The queries selected from samples can harvest most of the data in the original database;2) The queries with low overlapping rate in samples will also result in a low overlapping rate in the original database;and 3) The size of the sample and the size of the terms from where to select the queries do not need to be very large. Compared with other query selection methods, our method obtains the queries by analyzing a small set of sample documents, instead of learning the next best query incrementally from all the documents matched with previous queries. © 2012-IOS Press and the authors.

Predicting the future trajectory of multi-agent in dynamic scenarios is a crucial part of autonomous driving. Despite fruitful progress, existing methods still suffer from immatu-rity in tackling social interaction modeling, which is essential for trajectory prediction. A key reason is that the previous works only consider the interaction of a single category of agents while ignoring the influence between different types of agents. This paper contends a novel framework LG-LSTM to model local and global social interactions between different types of agents by scenario graph and attention fusion. It is mainly composed of two functional components: 1. LSTM-based interaction architecture consists of LSTM-based en-coding function, graph-aware encoding function, attention-fusion encoding function, and LSTM-based decoding function. 2. Multi-task training, which conducts trajectory pre-diction and multi-agent classification. Extensive experiments on two public autonomous driving benchmarks verify the ef-ficacy of the proposed techniques and achieve superior per-formance against state-of-the-art approaches. © 2022 IEEE.

The increasing demand of various networking applications such as Internet, voice, data, video and TV services inside large cities with large population requires the design and implementation of more effective metropolitan networks. Currently, several wireless networking systems were established to provide such services. Two main fixed broadband access network were used for such services: Local Multipoint Distribution Service (LMDS) and Multi-channel Multipoint Distribution Service (MMDS). Both of these systems face several problems such as: high cost, relatively low speed, small coverage area, and last-mile bottleneck. The effect of the above mentioned problems are more obvious when the network size increases. The deployment of a new technology by using Wireless Optical Mesh Network (WOMN), which use wireless optical communications between nodes, can overcome these problems and can provide more bandwidth, interference-free, frequency-free and more effectiveness in applications that require a real time responding like video surveillance. We investigate the WOMN advantages and disadvantages. We also discuss the commercial, geographical coverage and real time applicability. We will also investigate the challenges to deploy the new technique for local and metropolitan networks between different city buildings. © 2008 IEEE.

The need for survivability in optical networks is becoming more and more important because of the huge amount of aggregated traffic that is carried in an optical network. A number of protection schemes have been proposed for mesh networks, where their main objective is to provide a network that can restore a failure quickly and efficiently via a simple automated system. In this paper, we review and compare the protection schemes suitable for multicast traffic in optical networks with mesh topology. The schemes are compared with respect to network complexity and blocking probability. © 2008 IEEE.

Key management in wireless sensor networks (WSN) is a challenging problem because of the limited resources of sensor nodes and their vulnerability against physical attacks. In this paper, we present a Two Level Architecture key management scheme for wireless sensor networks (TLA). Our scheme combines efficiently different key management techniques in each architecture level. This combination gives TLA good performances in terms of key storage overhead as well as in terms of resistance degree against node capture. We compared TLA with most other proposed schemes and showed that, in most cases, our scheme gives the best overall performances. © 2008 IEEE.

In Mixed-Initiative Co-Creative tools, the human is mostly in control of what will and can be created, delegating the AI to a more suggestive role instead of a colleague in the co-creative process. Allowing more control and agency for the AI might be an interesting path in co-creative scenarios where AI could direct and take more initiative within the co-creative task. However, the relationship between AI and human designers in creative processes is delicate, as adjusting the initiative or agency of the AI can negatively affect the user experience. In this paper, different degrees of agency for the AI are explored within the Evolutionary Dungeon Designer (EDD) to further understand MI-CC tools. A user study was performed using EDD with three varying degrees of AI agency. The study highlighted elements of frustration that the human designer experiences when using the tool and the behavior in the AI that led to possible strains on the relationship. The paper concludes with the identified issues and possible solutions and suggested further research. Copyright © 2022, Association for the Advancement of Artificial Intelligence (***).

Stack Overflow (SO) platform has a huge dataset of questions and answers driven by interactions between users. But the count of unanswered questions is continuously rising, which is observed in various similar community Question & Answering platforms (Q&A) such as Yahoo, Quora and so on. To address this issue, these communities have explored clustering mechanisms to answer unanswered questions using other answered questions in the same cluster, which could also improve the response time for new questions. It is here, we propose SOCluster, an approach and a tool to cluster SO questions using a graph-based clustering approach. We selected four datasets of 10k, 20k, 30k & 40k SO questions without code-snippets or images involved, and performed clustering on them. We have done a preliminary evaluation of our tool by analyzing the resultant clusters using the commonly used metrics of Silhouette coefficient, Calinkski-Harabasz Index, & Davies-Bouldin Index. We performed clustering for 8 different threshold similarity values and analyzed the intriguing trends reflected by the output clusters through the three evaluation metrics. At 90% threshold similarity, it shows the best improvement for the three evaluation metrics on all four datasets. We further manually assessed the content in the clusters to confirm the similarity of elements in clusters. This revealed clusters to correspond to topics such as mouse over effect, speed optimisation, how to perform ĝsome' action in JavaScript, and so on. The source code and tool are available for download on Github at: https://***/rishalab/SOCluster, and the demo can be found here: https://***/Ewm-M_rg_x8. © 2023 ACM.
