Reproducibility Variable Result LLM Response
Research Type Experimental Experiments on the INEX 2009 entity ranking task show that the proposed approach achieves a significant improvement of the entity search performance (xinf AP from 0.27 to 0.39) over the existing solutions.

Pseudocode No The paper describes models and formulas but does not provide any explicitly labeled pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any statement or link indicating the availability of open-source code for the methodology described.
Open Datasets Yes We adopt a public-available document collection in our experiments: Wikipedia INEX 2009 collection2 (shorted as INEX09). 2http://www.mpi-inf.mpg.de/departments/d5/software/inex/
Dataset Splits No The paper mentions using the INEX 2009 entity ranking task dataset but does not specify the training, validation, or test dataset splits needed for reproduction.
Hardware Specification No The paper does not provide any specific details regarding the hardware used for conducting the experiments.
Software Dependencies No The paper mentions using the 'Wikipedia-Miner (Milne and Witten 2008)' toolkit but does not specify version numbers for it or any other software dependencies crucial for replication.
Experiment Setup Yes For the parameter h (L uses it for retrieving top-h relevant documents of a topic), we set h = 300 by default for LRCM and SRCM because larger h can only improve the precision very slightly. For the parameter λ, we adjust it and plot the results of L, S, LC and SC in Figure 1 respectively. It can be seen that the precision is stable for a wide range of λ. As such, we simply set λ = 0.5 for all the other experiments. For the parameter k of LCR+SCR, we find that the best performance is achieved when k = 20 in our experiments.
