Social network profiles as taste performances Hugo Liu (2007): Journal of Computer-Mediated Communication, 13(1), Blackwell Publishing.

This study examines how a social network profile's lists of interests--music, books, movies, television shows, etc.--can function as an expressive arena for taste performance. By composing interest tokens around a theme, profile users craft their "taste statements." First, socioeconomic and aesthetic influences on taste are considered, and the expressivity of ...

Small happiness: aesthetic strategies for witting consumers Hugo Liu (2007): Trans. Wu Gang. Cultural Review, November, 2007: 32-39.re, Shanghai

Beyond being moral and intellectual, we believe in our heart of hearts that true happiness endures and surpasses all tests of time--a criterion that sometimes proves too challenging for those who stake happiness on but a handful of epic life events. Felicitously, robustness is the strong suit of the small ... [English version]

From programming the unconscious to aesthetic technologies Hugo Liu, Paulo Urbano (2007): (interview), Nada 9, Portugal, nada.com.pt

My view of aesthetics is much closer to Freud"s. His insight was that the experience of art and beauty arises when everyday situations cause the unconscious mind to erupt with emotion. Using that revolutionary idea, Freud was able to interpret dreams and laughter--two central problems of aesthetics. Freud"s explanation emboldens ...

Introduction to the semantics of people and culture (editorial preface) Hugo Liu & Pattie Maes (2007): International Journal on Semantic Web and Information Systems, Special Issue on Semantics of People and Culture (Eds. H. Liu & P. Maes), 3(1), Hersey,PA: Idea Publishing Group.

The human-grown semantic web has already proven its great potential. By researching semantic technologies to exploit real-world system usage, to cope with subjectivity, and to enhance interpretation using cultural context, we can create smarter systems to harness and enhance humans" intrinsic semantic productivity.

Of men, women, and computers: data-driven gender modeling for improved user interfaces Hugo Liu & Rada Mihalcea (2007): Proceedings of the International Conference on Weblogs and Social Media, Boulder, CO, USA.

In this paper, we tried to gain insights into how men and women perceive day-by-day events, and what they most value in their daily experiences, by looking at a very large number of diary entries extracted from the blogosphere. Our analysis of gender distinctions revealed that women's and men's sensibilities ...

Superconsumer: a postmodern romance Hugo Liu (2006): (trans.), Nada 8, Portugal, nada.com.pt

But where is this in-between and how can a bricoleur find this space? Bhabha gives away the secret--it is located in "those moments or processes that are produced in the articulation of cultural differences." The bricoleur is accustomed to undermining one culture"s teachings with the teachings of another, but if ... [English version]

Unraveling the taste fabric of social networks Hugo Liu, Pattie Maes & Glorianna Davenport (2008): Social Networking Communities and E-Dating Services: Concepts and Implications (Eds: C. Romm-Livermore, K. Setzekorn), 18-43, Hershey,PA: Idea Group Inc. Originally published 2006 in International Journal on Semantic Web and Information Systems 2(1), 42-71.

Popular online social networks such as Friendster and MySpace do more than simply reveal the superficial structure of social connectedness--the rich meanings bottled within social network profiles themselves imply deeper patterns of culture and taste. If these latent semantic fabrics of taste could be harvested formally, the resultant resource would ...

Computing Point-of-View: Modeling and Simulating Judgments of Taste Hugo Liu (May, 2006): Ph.D. Dissertation, Program in Media Arts & Sciences, School of Architecture & Planning, MIT, Cambridge, MA, 163pp.

Our capacity for aesthetics and affectedness is one of the most celebrated bastions of humanity. Underlying our explicit knowledge and rationality is a faculty for judgment--the impulsion to prefer, to view the world through our individual lenses of taste. An interesting intellectual question is: can a computer model a person"s ...

Rendering aesthetic impressions of text in color space Hugo Liu & Pattie Maes (2006): International Journal on Artificial Intelligence Tools 15(4), 515-550, World Scientific Press.

What is an artwork and how could a machine become artist? This paper addresses the provocative question by theorizing a computational model of aesthetics and implementing the Aesthetiscope--a computer program that portrays aesthetic impressions of text and renders an abstract color grid artwork reminiscent of early twentieth century abstract expressionism. ...

Taste fabrics and the beauty of homogeneity Hugo Liu, Glorianna Davenport & Pattie Maes (2006): Association of Information Systems SIG SEMIS Bulletin, vol. 3.

Whereas ontology and metadata systems are bloating with semantic relation diversity, a semantic fabric is homogenous in its relation type (they are all affinity scores) and its method of reasoning (spreading activation). Because a semantic fabric represents just one semantic dimension, it can do it exhaustively and yield a very ...

Self-reflexive performance: dancing with the computed audience of culture Hugo Liu & Glorianna Davenport (2005): International Journal of Performance Arts and Digital Media 1(3), 237-247, Intellect Ltd.

Typically performance is a display for others, and is time-limited. But if we also regard everyday life as a performance, we see that it is a continuous improvisation--a multi-faceted dance with an audience that is our social and cultural milieu. In moments of self-reflection, we ourselves motivate this performance, seizing ...

Synesthetic Recipes: foraging for food with the family, in taste-space Hugo Liu, Matthew Hockenberry & Ted Selker (2005): Proceedings of the 32nd Annual Conference on Computer Graphics and Interactive Techniques, SIGGRAPH 2005, Los Angeles.

This paper presents a new answer to one very old question, "What's for dinner?" Synesthetic Recipes is a graphical interface which allows a person to brainstorm dinner recipe ideas by describing how they imagine the recipe should taste (e.g. "hearty, mushy, moist, aromatic"); to keep mindful of the tastebuds of ...

The aesthetiscope: visualizing aesthetic readings of text in color space Hugo Liu & Pattie Maes (2005b): Proceedings of the Eighteenth International Florida Artificial Intelligence Research Society Conference (AI in Music & Art Special Track), 74-79. Menlo Park, Calif.: AAAI Press.

Moorman & Ram"s revolt against the grain of the classical AI narrative understanding literature emboldens us in our task of aesthetic reading, which is the topic of this paper. Aesthetic reading is not reading purely for information. It is an emotionalized and personal reading, whereby the text"s primary purpose is ...

InterestMap: harvesting social network profiles for recommendations Hugo Liu & Pattie Maes (2005a): Proceedings of IUI Beyond Personalization 2005: A Workshop on the Next Stage of Recommender Systems Research, January 9, 2005, San Diego, CA, USA, 54-59.

Another confluence feature is a taste clique. Visible in Figure 2, for example, we can see that "Sonny Rollins," is straddling two cliques with strong internal cohesion. While the identity descriptors are easy to articulate and can be expected to be given in the special interests category of the profile, ...

Articulation, the letter, and the spirit in the aesthetics of narrative Hugo Liu (2004): Proceedings of the 2004 ACM Workshop on Story Representation, Mechanism, and Context (SRMC'04), New York.

We posed the aesthetics of narrative as problematics of articulation, the letter, and the spirit. We established the letter as the agency of social language, of the explicit, known, mundane, habituated, and thus, unaesthetic. In contrast, the spirit is the agency of the aesthetic; it is an amorphous, anomic space ...

Visualizing the affective structure of a text document Hugo Liu, Ted Selker & Henry Lieberman (2003): Proceedings of the Conference on Human Factors in Computing Systems, CHI 2003, April 5-10, 2003, Ft. Lauderdale, FL, USA, 740-741, ACM Press.

This paper introduces an approach for graphically visualizing the affective structure of a text document. A document is first affectively analyzed using a unique textual affect sensing engine, which leverages commonsense knowledge to classify text more reliably and comprehensively than can be achieved with keyword spotting methods alone. Using this ...

Saurus: an emotionally-weighted thesaurus Jim Gouldstone, Hugo Liu, Henry Lieberman & Hiroshi Ishii (2006): Proceedings of the AAAI-06 Workshop on Computational Aesthetics, 107-110, AAAI Press.

Saurus produces interesting results for larger bodies of text as well. In a speech made in Sept. 2005, U.S. Senator John Kerry criticized the government's response to Hurricane Katrina's devastation of New Orleans: "The incompetence of Katrina's response is not reserved to a hurricane. There's an enormous gap between American's ...

NLP (natural language processing) for NLP (natural language programming) Rada Mihalcea, Hugo Liu & Henry Lieberman (2006): A Gelbukh (Ed.) Computational Linguistics and Intelligent Text Processing, LNCS 3878, 319-330, Springer.

Write a program to generate 10000 random numbers between 0 and 99 inclusive. You should count how many of times each number is generated and write these counts out to the screen.

Feasibility studies for programming in natural language Henry Lieberman & Hugo Liu (2006): Lieberman, Paterno, Wulf (Eds.): End-User Development (Human-Computer Interaction Series Vol. 9), 459-474, Springer.

Pane and Myers conducted studies asking non-programming fifth-grade users to write descriptions of a Pac-Mac game (in another study, college students were given a spreadsheet programming task). The participants also drew sketches of the game so they could make deictic references. Pane and Myers then analyzed the descriptions to discover ...

Langutils: a natural language toolkit for common lisp Ian Eslick & Hugo Liu (2005): Proceedings of the International Lisp Conference (ILC'2005), Stanford, CA, June 2005.

This paper describes the design and implementation of "langutils," a high-performance natural language toolkit for Common Lisp. We introduce the techniques of real-world NLP and explore tradeoffs in the representation and implementation of tokenization, part-of-speech tagging, and parsing. The paper concludes with a discussion of the use of the toolkit ...

Programmatic semantics for natural language interfaces Hugo Liu & Henry Lieberman (2005b): Proceedings of the ACM Conference on Human Factors in Computing Systems, CHI 2005, April 5-7, 2005, Portland, OR, USA, 1597-1600 ACM Press.

Perhaps one reason for the absence of explicit looping in natural language is that there already exists basic linguistic constructions that imply a class of procedure which reasons about sets using relational descriptions (e.g. "sweet drinks" as a subset of "drinks"); these set-theoretic constructions seem to supplant the need to ...

Metafor: visualizing stories as code Hugo Liu & Henry Lieberman (2005a): Proceedings of the ACM International Conference on Intelligent User Interfaces, IUI 2005, January 9-12, 2005, San Diego, CA, USA, 305-307, ACM Press.

As a person types a story into Metafor, the system continuously updates a side-by-side "visualization" of the person"s narrative as scaffolding code. This code may not be directly executable, but it is meant to help a person reify her thoughts. We believe that Metafor is a novel system which can ...

Toward a programmatic semantics of natural language Hugo Liu & Henry Lieberman (2004): Proceedings of VL/HCC'04: the 20th IEEE Symposium on Visual Languages and Human-Centric Computing, 281-282. September 26-29, 2004, Rome, IEEE Computer Society Press.

Natural language is also generic enough to use the same syntax to declare and compute variables, a manner similar to generic functions of the Common LISP Object System (e.g. "Pacman eats yellow dots" can depending on what"s known, declare that dots are yellow, or apply "eat" only to the subset ...

Unpacking meaning from words Hugo Liu (2003): Blackburn et al. (Eds.): Modeling and Using Context, LNCS 2680, 218-232, Springer.

No coherent meaning without simulation. In the Bubble Lexicon graph, different and possibly conflicting meanings can attach to each word-concept node; therefore, words hardly have any coherent meaning in the static view. We suggest that when human minds think about what a word or phrase means, meaning is always evaluated ...

Commonsense reasoning in and over natural language Hugo Liu & Push Singh (2004): M Negoita, RJ Howlett, LC Jain (Eds.): Knowledge-Based Intelligent Information and Engineering Systems, LNCS 3215, 293-306, Springer.

For example, what is the precise color of a "red apple?" In logic, we might be able to formally represent the range in the color spectrum corresponding to a "red apple," but in natural language, the word "red" is imprecise and has various interpretations. Consider the differing colors which map ...

Beating common sense into interactive applications Henry Lieberman, Hugo Liu, Push Singh & Barbara Barry (2004): Artificial Intelligence Magazine 25(4), 63-76, AAAI Press.

Things fall down, not up. Weddings (sometimes) have a bride and a groom. If someone yells at you, they"re probably angry. One of the reasons that computers seem dumber than humans is that they don"t have common sense--a myriad of simple facts about everyday life and the ability to make ...

Teaching machines about everyday life Push Singh, Barbara Barry & Hugo Liu (2004), BT Technology Journal 22(4), 227-240, Kluwer Academic Publishers.

We were interested in the question of whether it was possible to distribute the problem of building a commonsense knowledge base across thousands of people on the Web, and especially, people with little or no special training in computer science or artificial intelligence. We were interested in whether the "average ...

Semantic Understanding and Commonsense Reasoning in an Adaptive Photo Agent Hugo Liu (May, 2002): Master's Thesis, School of EECS, Massachusetts Institute of Technology, Cambridge, MA, 160pp.

We investigated three broad properties of intelligent software agents -- communication through and understanding human language; exercising some commonsense to prevent obvious mistakes; and learning from past user interactions to improve future interactions. The ARIA Photo Agent provided an application platform from which approaches to these properties were tested, and ...

Makebelieve: using commonsense knowledge to generate stories Hugo Liu & Push Singh (2002): Proceedings of the Eighteenth National Conference on Artificial Intelligence, AAAI 2002, July 28 - August 1, 2002, Edmonton, Alberta, Canada, 957-958, AAAI Press.

Makebelieve, an interactive story generation agent that can generate short fictional texts of 5 to 20 lines when the user supplies the first line of the story. Our fail-soft approach to story generation represents a hybrid approach inheriting from both the structuralist and transformationalist traditions. It also incorporates a novel ...

Robust photo retrieval using world semantics Hugo Liu & Henry Lieberman (2002): Proceedings of the LREC 2002 Workshop on Creating and Using Semantics for Information Retrieval and Filtering: State-of-the-art and Future Research, Las Palmas, Canary Islands, 15-20, LREC Press.

In our photo domain, we propose a mechanism for robust retrieval by expanding the concepts depicted in the photos, thus going beyond lexical-based expansion. Because photos often depict places, situations and events in everyday life, concepts depicted in photos such as place, event, and activity can be expanded based on ...
