Msc Thesis Presentation
Rui Pereira's thesis proposes a new approach to querying model-driven spreadsheets. Existing spreadsheet querying methods like Google Query are restrictive and counterintuitive. The proposed QuerySheet system infers the data model from spreadsheet structure and allows intuitive SQL-like queries. A preliminary study found QuerySheet was faster and more intuitive than Google Query. The thesis contributes a prototype and papers on model-driven spreadsheet querying. Future work includes improving denormalization handling and developing a graphical querying interface.

HIEDS: A Generic and Efficient Approach to Hierarchical Dataset Summarization
This document summarizes the HIEDS approach to hierarchical dataset summarization. HIEDS aims to provide multigranular summaries that preserve dataset structure and are comprehensible. It models summarization as a multidimensional knapsack problem to maximize subgroup cohesion and moderateness while disallowing large overlap. HIEDS uses a greedy strategy for efficient solving but requires non-trivial implementation. Experiments show HIEDS outperforms the baseline by generating hierarchical rather than flat groups with better trade-offs and less redundancy.

Generating Compact and Relaxable Answers to Keyword Queries over Knowledge Gr...
This document presents an algorithm called CORE for generating compact yet relaxable answers to keyword queries over knowledge graphs. CORE aims to balance answer compactness, defined as having a bounded diameter, with answer completeness, defined as covering the most query keywords. It provides theoretical foundations for the existence of such answers and uses a best-first search approach. An evaluation shows CORE efficiently computes answers that are more complete than alternatives while remaining compact.
Semantic Data Retrieval: Search, Ranking, and Summarization
Gong Cheng presented on semantic data retrieval, including entity retrieval and association retrieval from semantic graphs. He discussed two main challenges: efficiently searching large graphs for associations within a diameter bound, and ranking the retrieved associations. For the first challenge, he proposed algorithms using path finding, pruning, and result deduplication. For the second challenge, he conducted a user study and found that association size was the most important ranking factor. Other proposed measures like entity homogeneity and relation heterogeneity had mixed user preferences.
Semantic Web related top conference review
The document summarizes key topics in semantic web and knowledge graph research from 2014-2017, including conferences, hot research areas, applications, and papers. It discusses trends such as increasing focus on knowledge graph applications, integration, and construction using techniques like neural networks. Notable news includes Google calling for dataset metadata and Wikidata creating its 31 millionth entity. The road ahead may involve greater knowledge graph commercialization, enrichment, and making knowledge graphs more accessible on the Web.
Relatedness-based Multi-Entity Summarization
The document proposes a new approach called relatedness-based multi-entity summarization (MES) to generate concise summaries of related entities. It formulates MES as a quadratic multidimensional knapsack problem (QMKP) to select important and diverse intra-entity features while also selecting inter-entity features that indicate relatedness. It presents an algorithm called REMES based on the grasp heuristic to solve the QMKP formulation. A user study shows REMES outperforms other entity summarization methods at multi-entity summarization tasks.
Generating Illustrative Snippets for Open Data on the Web
We propose generating illustrative snippets from datasets to serve with metadata on dataset search engines. Currently, only metadata is shown. Snippets would help users understand the contents faster by covering important types and entities, using familiar entities, and keeping entities related. We formulate the snippet generation as a maximum-weight-and-coverage connected graph problem to optimize for these qualities. Experimental results show our snippets outperform baselines.
Efficient Algorithms for Association Finding and Frequent Association Pattern...
The document presents efficient algorithms for association finding and frequent association pattern mining in large graph data. It describes the problems of finding all associations connecting a set of query entities within a diameter constraint and mining frequent association patterns. The basic solutions and optimizations for association finding using distance-based pruning and distance oracles are discussed. For frequent pattern mining, it addresses generating a canonical code to uniquely represent patterns and counting code occurrences to determine frequency. Experiments on real datasets demonstrate the efficiency and scalability of the approaches.
Summarizing Semantic Data
This document discusses summarizing semantic data, including entity descriptions, entity associations, and semantic datasets. It describes extractive and abstractive summarization methods. For entity descriptions, intrinsic metrics like frequency, centrality, informativeness, and diversity are used to rank property-value pairs for the summary. Extrinsic metrics also utilize external knowledge and context. Similar methods are applied to summarizing entity associations by ranking paths between entities. Summarizing semantic datasets involves selecting a representative subset of the data.
Taking up the Gaokao Challenge: An Information Retrieval Approach
This document describes an information retrieval approach for answering questions from the Gaokao, China's national college entrance exam. It retrieves relevant concept pages, quotes, and disambiguates terms from Wikipedia. It ranks pages based on centrality within vector spaces of words, links, and categories, filtering within relevant historical categories. It assesses answer options based on the extent the question and pages can entail each option. In experiments, it correctly answered 43.09% of questions answerable from Wikipedia and 31.28% of questions outside Wikipedia's scope.

This document describes Explass, a system for exploring associations between entities via top-k ontological patterns and facets. It discusses challenges in exploring the over 1,000 associations within 4 hops in DBpedia and proposes two exploration methods: clustering associations into patterns and using entity/property classes as facets. The key steps involve mining significant patterns as frequent itemsets and selecting k patterns based on frequency, informativeness, and overlap. A demo of Explass on DBpedia is presented along with results of a user study comparing it to other approaches.
Facilitating Human Intervention in Coreference Resolution with Comparative En...
The document presents a method for facilitating human intervention in coreference resolution by providing comparative entity summaries. It describes using properties and values of candidate coreferent entities to generate summaries that reflect their commonality and differences. The optimal summary maximizes commonality, difference, identity information and diversity, subject to a length limit. An evaluation involved human subjects verifying coreferent relationships for different summarization approaches. The comparative summary approach was found to improve verification efficiency without affecting accuracy as much as only showing common properties or entire descriptions.
Towards Exploratory Relationship Search: A Clustering-based Approach
This document presents an approach for exploratory relationship search through hierarchical clustering. It aims to address the challenge of too many relationship search results by organizing them into a cluster hierarchy based on common relationship patterns. An evaluation with participants performing lookup and exploratory search tasks on DBpedia data found that the clustering approach outperformed simple listing and faceted categorization alternatives. User feedback suggested areas for improvement like more concise visualizations and cognitive support. The authors conclude it is a promising approach and future work could combine facets and clustering or explore alternatives.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
