Cranfield is Dead; Long Live Cranfield
Evaluating search system effectiveness is a foundational hallmark of information retrieval research. Doing so requires infrastructure appropriate for the task at hand, which has frequently entailed using the Cranfield paradigm: test collections and associated evaluation measures. Observers have declared Cranfield moribund multiple times in its 60 year history, though each time test collection construction techniques and evaluation measure definitions have evolved to restore Cranfield as a useful tool. Now Cranfield's effectiveness is once more in question since corpora sizes have grown to the point that finding a few relevant documents is easy enough to saturate high-precision measures while deeper measures are unstable because too few of the relevant documents have been identified. In this talk I'll review how Cranfield evolved in the past and examine its prospects for the future.conference pape
LIPI at the NTCIR-16 FinNum-3 Task: Ensembling transformer based models to detect in-claim numerals in Financial Conversations
The third edition of FinNUM shared task, being held with NTCIR-16 presented the challenge of classifying numerals present in financial texts into in-claim or out-of-claim classes. It consisted of two claim detection sub-tasks on i) professional analysts’ reports written in Chinese and ii) earning conference calls transcribed in English. In this paper, we describe the approach our team (LIPI) followed while participating in the English subtask of FinNUM3. This approach consists of ensembling transformer based models with a Logistic Regression model trained using BERT embeddings and handcrafted features. It out-performed the existing baseline and achieved a macro F1 score of 84.73% and micro F1 score of 95.59% on the test set.conference pape
nukl's QA System at the NTCIR-16 QA Lab-PoliInfo-3
Our nukl team participated in the NTCIR-16 QA Lab-PoliInfo-3's question answering (QA) subtask. This paper describes the QA system for Japanese assembly member speeches using T5. We generated answer summaries using two input types: the answerer's entire utterance and the answer text corresponding to the input question. We made two T5 models for each input and determined the final output according to the length of the answerer's utterance. Our system achieved the highest score in both automatic and human evaluations in this subtask.conference pape
MM6 at the NTCIR-16 Session Search Task
A single query may hardly satisfy the user’s information needs, so that users will continuously submit more queries to the search system until they are satisfied or stop trying. This search process is called session search. The MM6 team participated in the IR subtask of the NTCIR-16 Session Search Task. This paper reports our three approaches for FOSS task and one approach for POSS task. We display and discuss the official results at the end.conference pape
THUIR2 at NTCIR-16 Session Search (SS) Task
Our team(THUIR2) participated in both FOSS and POSS subtasks of the NTCIR-16. Session Search (SS) Task. This paper describes our approaches and results. In the FOSS subtask, we submit five runs by using a learning-to-rank model and a fine-tuned pre-trained language model. We fine-tune the pre-trained language model with both ad-hoc data and session information and then assembled them by a learning-to-rank method. The assembled model achieves the best performance among all participants in the preliminary evaluation. In the POSS subtask, we used an assembled model which also achieves the best performance in the preliminary evaluation.conference pape
