{"results":[{"id":"arxiv_2511.20606","title":"Limit Order Book Dynamics in Matching Markets: Microstructure, Spread, and Execution Slippage","authors":[{"name":"Yao Wu"}],"abstract":"Conventional models of matching markets assume that monetary transfers can clear markets by compensating for utility differentials. However, empirical patterns show that such transfers often fail to close structural preference gaps. This paper introduces a market microstructure framework that models matching decisions as a limit order book system with rigid bid ask spreads. Individual preferences are represented by a latent preference state matrix, where the spread between an agent's internal ask price (the unconditional maximum) and the market's best bid (the reachable maximum) creates a structural liquidity constraint. We establish a Threshold Impossibility Theorem showing that linear compensation cannot close these spreads unless it induces a categorical identity shift. A dynamic discrete choice execution model further demonstrates that matches occur only when the market to book ratio crosses a time decaying liquidity threshold, analogous to order execution under inventory pressure. Numerical experiments validate persistent slippage, regional invariance of preference orderings, and high tier zero spread executions. The model provides a unified microstructure explanation for matching failures, compensation inefficiency, and post match regret in illiquid order driven environments.","source":"arXiv","year":2025,"language":"en","subjects":["q-fin.TR","cs.MA","cs.SI"],"url":"https://arxiv.org/abs/2511.20606","pdf_url":"https://arxiv.org/pdf/2511.20606","is_open_access":true,"published_at":"2025-11-25T18:34:46Z","score":69},{"id":"arxiv_2503.20793","title":"Semantic Web and Software Agents -- A Forgotten Wave of Artificial Intelligence?","authors":[{"name":"Tapio Pitkäranta"},{"name":"Eero Hyvönen"}],"abstract":"The history of Artificial Intelligence (AI) is a narrative of waves -- rising optimism followed by crashing disappointments. AI winters, such as the early 2000s, are often remembered as barren periods of innovation. This paper argues that such a perspective overlooks a crucial wave of AI that seems to be forgotten: the rise of the Semantic Web, which is based on knowledge representation, logic, and reasoning, and its interplay with intelligent Software Agents. Fast forward to today, and ChatGPT has reignited AI enthusiasm, built on deep learning and advanced neural models. However, before Large Language Models (LLMs) dominated the conversation, another ambitious vision emerged -- one where AI-driven Software Agents autonomously served Web users based on a structured, machine-interpretable Web. The Semantic Web aimed to transform the World Wide Web into an ecosystem where AI could reason, understand, and act. Between 2000 and 2010, this vision sparked a significant research boom, only to fade into obscurity as AI's mainstream narrative shifted elsewhere. Today, as LLMs edge toward autonomous execution, we revisit this overlooked wave. By analyzing its academic impact through bibliometric data, we highlight the Semantic Web's role in AI history and its untapped potential for modern Software Agent development. Recognizing this forgotten chapter not only deepens our understanding of AI's cyclical evolution but also offers key insights for integrating emerging technologies.","source":"arXiv","year":2025,"language":"en","subjects":["cs.SI","cs.CY","cs.DL"],"url":"https://arxiv.org/abs/2503.20793","pdf_url":"https://arxiv.org/pdf/2503.20793","is_open_access":true,"published_at":"2025-03-20T12:55:48Z","score":69},{"id":"arxiv_2407.18275","title":"Relations between average clustering coefficient and another centralities in graphs","authors":[{"name":"Mikhail Tuzhilin"}],"abstract":"Relations between average clustering coefficient and global clustering coefficient, local efficiency, radiality, closeness, betweenness and stress centralities were obtained for simple graphs.","source":"arXiv","year":2024,"language":"en","subjects":["cs.SI","physics.soc-ph"],"url":"https://arxiv.org/abs/2407.18275","pdf_url":"https://arxiv.org/pdf/2407.18275","is_open_access":true,"published_at":"2024-07-23T15:29:37Z","score":68},{"id":"arxiv_2412.03601","title":"Relations between average shortest path length and another centralities in graphs","authors":[{"name":"Mikhail Tuzhilin"}],"abstract":"Relations between average shortest path length and average clustering coefficient, radiality, closeness and stress centralities were obtained for simple graphs.","source":"arXiv","year":2024,"language":"en","subjects":["cs.SI","math.CO"],"url":"https://arxiv.org/abs/2412.03601","pdf_url":"https://arxiv.org/pdf/2412.03601","is_open_access":true,"published_at":"2024-12-03T09:05:50Z","score":68},{"id":"arxiv_2309.16507","title":"Innovation Modeling Grid","authors":[{"name":"Oliver Klemp"}],"abstract":"This technical document presents the committee driven innovation modeling methodology \"Innovation Modeling Grid\" in detail.

In arXiv:1807.09596 [cs.SI], the second author studied this problem in the setting of sparse graphs with high-dimensional node-covariates. Using the non-rigorous cavity method from statistical physics, they conjectured the sharp limits for community detection in this setting. Further, the information theoretic threshold was verified, assuming that the average degree of the observed graph is large. It is expected that the conjecture holds as soon as the average degree exceeds one, so that the graph has a giant component. We establish this conjecture, and characterize the sharp threshold for detection and weak recovery.","source":"Semantic Scholar","year":2020,"language":"en","subjects":["Mathematics","Computer Science"],"url":"https://www.semanticscholar.org/paper/c839a775827327b0e6cc84051d2f457da17f6116","is_open_access":true,"citations":23,"published_at":"","score":64.69},{"id":"ss_87998332d8ddc2ad47aec83d460f3b00831798b5","title":"Fuzzy Set Model of Dengue Using Imageries and the Geographic Information System in Palambang","authors":[{"name":"Cipta Estri Sekarrinia"},{"name":"Syamsul Bachric"},{"name":"Didik Taryanad"}],"abstract":"","source":"Semantic Scholar","year":2020,"language":"en","subjects":null,"url":"https://www.semanticscholar.org/paper/87998332d8ddc2ad47aec83d460f3b00831798b5","is_open_access":true,"citations":1,"published_at":"","score":64.03},{"id":"arxiv_2011.05801","title":"A Small Survey On Event Detection Using Twitter","authors":[{"name":"Debanjan Datta"}],"abstract":"A small survey on event detection using Twitter.
