Abstract: Reading Comprehension tests are commonly used to assess the degree to which people comprehend what they read. This is why we work with the hypothesis that it is reasonable to use these tests to assess the degree to which a machine "comprehends" what it is reading. In this work, we evaluate Question Answering systems using Reading Comprehension tests from exams to enter University. This article analyses the datasets generated, the kind of inferences required, the methodology followed in three evaluation campaigns, the approaches presented by participants and current results. Besides, we study the evolution of systems and the main lessons learned in this evaluation process. We also show how current technologies are unable to pass university-entrance exams. This is because these tests require a deep understanding of texts, as well as detecting the similar meaning of phrases with different words. Future directions focused on these ideas seem more promising than including a massive amount of data for training systems, what has allowed systems to obtain outstanding results in Reading Comprehension tests with more straightforward questions. We think this study helps to increase the knowledge about how to develop better Question Answering systems.

2Hu, X. ; Kando, N.: Task complexity and difficulty in music information retrieval.
In: Journal of the Association for Information Science and Technology. 68(2017) no.7, S.1711-1723.
Abstract: There has been little research on task complexity and difficulty in music information retrieval (MIR), whereas many studies in the text retrieval domain have found that task complexity and difficulty have significant effects on user effectiveness. This study aimed to bridge the gap by exploring i) the relationship between task complexity and difficulty; ii) factors affecting task difficulty; and iii) the relationship between task difficulty, task complexity, and user search behaviors in MIR. An empirical user experiment was conducted with 51 participants and a novel MIR system. The participants searched for 6 topics across 3 complexity levels. The results revealed that i) perceived task difficulty in music search is influenced by task complexity, user background, system affordances, and task uncertainty and enjoyability; and ii) perceived task difficulty in MIR is significantly correlated with effectiveness metrics such as the number of songs found, number of clicks, and task completion time. The findings have implications for the design of music search tasks (in research) or use cases (in system development) as well as future MIR systems that can detect task difficulty based on user effectiveness metrics.

3Fujii, A. ; Iwayama, M. ; Kando, N.: Introduction to the special issue on patent processing.
In: Information processing and management. 43(2007) no.5, S.1149-1153.
Abstract: The processing of intellectual property documents, such as patents, has been important to the industry, business, and law communities. Recently, the importance of patent processing has also been recognized in academic research communities, particularly by information retrieval and natural language processing researchers. In addition, large test collections that include patents have recently become available, to enable the systematic evaluation of methodologies from a scientific point of view. In the light of these activities, this special issue is intended to collect advanced research papers on patent processing. As an introduction to the special issue on patent processing, this paper surveys the relevant literature and outlines the papers selected for the special issue.

In: Information processing and management. 41(2005) no.3, S.415-432.
Abstract: This introductory paper covers not only the research content of the articles in this special issue of IP&M but attempts to characterize the state-of-the-art in the Cross-Language Information Retrieval (CLIR) domain. We present our view of some major directions for CLIR research in the future. In particular, we find that insufficient attention has been given to the Web as a resource for multilingual research, and to languages which are spoken by hundreds of millions of people in the world but have been mainly neglected by the CLIR research community. In addition, we find that most CLIR evaluation has focussed narrowly on the news genre to the exclusion of other important genres such as scientific and technical literature. The paper concludes by describing an ambitious 5-year research plan proposed by James Mayfield and Paul McNamee.

In: International forum on information and documentation. 19(1994) no.2, S.20-24.
Abstract: Discusses and categorizes suitable information concepts for the context of LIS into 3 groups: objective information, subjective information, and information as process. Examines the characteristics of each group to indicate their relationships with each other
