A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.  相似文献   

The rise of the machines: Artificial intelligence meets scholarly content          下载免费PDF全文

Alex D. Wade  Kuansan Wang 《Learned Publishing》2016,29(3):201-205

Key points

• New forms of human/machine dialogue are emerging as robots understand vast amounts of content rather than simply indexing content as strings of characters.
• Recognizing strings of characters as entities (e.g. = names = authors) allows for meaningful associations between entities and reasoning over these relationships.
• Web‐scale adoption of the Semantic Web approach has been slow because it is too complex to implement and does not scale.
• User intent, discovered through conversational models of human–computer interaction, allows for a deeper understanding of exactly what researchers are looking for.
• Personal agents hold the promise of finding information that we will find useful before we have started to look for it.
• Publishers can use Academic Knowledge APIs to interpret academic user queries and find rich information from the Microsoft Academic Graph.

Look who’s talking: Emergent evidence for discriminating between differences in listserv participation     

Alex Pomson 《Education and Information Technologies》2008,13(2):147-163

This paper reports findings from a study of LookJed, the oldest and largest on-line forum for Computer Mediated Discussion among individuals interested in Jewish education. The study adopted a “cyber-ethnographic” approach, with postings to the forum seen as “acts of communication” that reveal what is important to their authors. An interest in exploring similarities between forum conversations and those in teachers’ lounges led to an investigation of Herring’s claim that most listservs do not include discussion at all, only the trading of information. This investigation found that active forum participants generally use the forum for discrete purposes, most commonly to exchange information about “subject matter” or “teaching material”, less commonly to exchange opinions and ideas, and rarely to do both. Integrating an analysis of patterns of contribution with an examination of their discursive content reveals six preeminent “types” among the population of contributors, each of whom participates in the forum in different ways and acts with different purposes. Although this typology is at best suggestive and needs to be tested against other listserv cases, its easy identification suggests that in order to better understand the cultures of virtual forums, it is important to pursue a more variegated characterization of listserv participants and their motivations than has typically been the case in CMD research where users are most frequently identified as either lurkers or fanatics, or as active or passive participants.  相似文献

Ego depletion negatively affects knowledge retrieval in secondary school students     

Chris Englert  Alex Bertrams 《教育心理学》2017,37(9):1057-1066

In the present study, we tested the assumption that performance in a knowledge retrieval test would be lower in secondary school students with temporarily depleted self-control strength (n = 53) compared to secondary school students with temporarily available self-control strength (n = 56). After manipulating self-control strength, students were instructed to memorise the names and the functions of the human eye and to recall as many names and functions as possible following a one-min distraction task. The results supported our assumptions, as students with depleted self-control strength performed significantly worse in the knowledge retrieval task compared to students whose self-control strength had not been temporarily depleted. The results suggest that depleted self-control strength may negatively affect academic performance and hinder a successful academic career. The theoretical and practical implications of these findings are discussed.  相似文献   

Assessing the Psychometric Properties of the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form in Mainland China     

Ke Fang  Alex L Pieterse  Myrna Friedlander  Junhong Cao 《International journal for the advancement of counseling》2011,33(4):309-321

This investigation tested the psychometric properties of the Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF; Fisher and Farina [Journal of College Student Development, 36, 368–373, 1995]) in a sample of 338 Mainland Chinese college students. Using back-translation, the ATSPPH-SF was translated into simplified Chinese. Confirmatory factor analysis did not support the original one-factor model. Subsequently, exploratory factor analysis suggested a 7-item, two-factor model; however, the new factor structure yielded poor reliability coefficients, below .60. Results suggest that the help-seeking construct as operationalized by the ATSPPH-SF may not be valid for the Chinese population. The importance of designing indigenous instruments for help-seeking attitudes is discussed.  相似文献
