The FRDC team participated in the IMine task of the NTCIR11, including subtopic mining and document ranking subtasks for Chinese language. In the subtopic mining subtask, we propose two methods to build the two-level hierarchy subtopics. Our methods gain high F-score and H-score respectively. In the document ranking subtask, we adopt various features for relevant webpage retrieval and document ...

Intuitionistic fuzzy sets theory which is the generalisation of fuzzy sets theory is more suitable tool for dealing with imprecise information. The information provided by the decision maker is imprecise in many situations. So, intuitionistic fuzzy preference relation is a suitable tool for such cases. The estimation of the priority vector of the intuitionistic fuzzy preference relation is an i...

Many decisions need to be made based on imprecise or incomplete initial information. In such cases, decision makers are generally more interested in some sets of the most promising solutions rather than the best single solution. Therefore, in contrast to conventional optimisation approaches that aim to find exact optimal points, we aim to find optimal ranges with variable satisfaction degrees. ...

In collaborative play, children exhibit different levels of engagement. Some children are engaged with other children while some play alone. In this study, we investigated multimodal detection of individual levels of engagement using a ranking method and non-verbal features: turn-taking and body movement. Firstly, we automatically extracted turn-taking and body movement features in naturalistic...

In many real life optimization problems, the parameters are often imprecise and are difficult to be represented in discrete quantity. One of the approaches to model such situation is considering these imprecise parameters as intuitionistic fuzzy numbers and then approximating these by its expected interval value. Further in process of solution, membership function for each objective function ar...

Fuzzy set has been applied in many real applications to handle uncertainty. The aim of the paper is to study the replacement problem with uncertainty. This problem involves capital cost, scrap value or salvage value, maintenance cost or operating cost, and rate of interest having an imprecise value. Here, we assume the imprecise values as positive trapezoidal fuzzy numbers. Moreover, we conside...

In the Semantic Web context information would be retrieved, processed, shared, reused and aligned in the maximum automatic way possible. Our experience with such applications in the Semantic Web has shown that these are rarely a matter of true or false but rather procedures that require degrees of relatedness, similarity, or ranking. Apart from the wealth of applications that are inherently imp...

Abstract This paper deals with an improved version of the deck cards method to render construction ratio and interval scales more “accurate” compared ones built in original version. The improvement comes from fact that we can account for a richer finer preference information provided by decision-maker, which permits accurate modeling strength between different levels scale. Instead considering ...

in this paper, presenting two simple methods for ranking of efficient dmus in dea models that included to add one virtual dmu as ideal dmu and is using the additive model. note that, we use an ideal point just for comparing efficient dmus with. although these methods are simple, they have ability for ranking all efficient dmus, extreme points and the others, also they are capable of ranking the...
