Structured Preference Representation and Multiattribute Auctions
Handling preferences over multiple objectives (or attributes) poses serious challenges to
the development of automated solutions to complex decision problems. The number of
decision outcomes grows exponentially with the number of attributes, and that makes elicitation,
maintenance, and reasoning with preferences particularly complex. This problem can potentially be alleviated by using a factored representation of preferences based on
independencies among the attributes. This work has two main components.
The first component focuses on development of graphical models for multiattribute
preferences and utility functions. Graphical models take advantage of factored utility, and
yield a compact representation for preferences. Specifically, I introduce CUI networks, a
compact graphical representation of utility functions over multiple attributes. CUI networks
model multiattribute utility functions using the well studied utility independence concept.
I show how conditional utility independence leads to an effective functional decomposition
that can be exhibited graphically, and how local conditional utility functions, depending on
each node and its parents, can be used to calculate joint utility.
The second main component deals with the integration of preference structures and
graphical models in trading mechanisms, and in particular in multiattribute auctions. I first
develop multiattribute auctions that accommodate generalized additive independent (GAI)
preferences. Previous multiattribute mechanisms generally either remain agnostic about
tradersâ preference structures, or presume highly restrictive forms, such as full additivity. I present an approximately efficient iterative auction mechanism that maintains prices on potentially overlapping GAI clusters of attributes, thus decreasing elicitation and computation burden while allowing for expressive preference representation.
Further, I apply preference structures and preference-based constraints to simplify the
particularly complex, but practically useful domain of multi-unit multiattribute auctions
and exchanges. I generalize the iterative multiattribute mechanism to a subset of this domain, and investigate the problem of finding an optimal set of trades in multiattribute call
markets, given restrictions on preference expression. Finally, I apply preference structures to simplify the modeling of user utility in sponsored-search auctions, in order to facilitate ranking mechanisms that account for the user experience from advertisements. I provide short-term and long-term simulations showing the effect on search-engine revenues.Ph.D.Computer Science & EngineeringUniversity of Michigan, Horace H.

Essays on the Rationality of Online Romance Scammers
The rapid development of the internet has served an essential role in providing communication platforms for people to choose to have personal interactions. One manifestation is using social media platforms and dating services to establish social relationships. The use of online platforms has also provided unscrupulous individuals with malicious intent the ability to target vulnerable victims using bogus romantic intent to obtain money from them. This type of newly evolved cybercrime is called an online romance scamming. To date, online romance scams have spread to every part of the world (i.e., mainly in the United States, China, Canada, Australia, and the UK) and caused considerable financial and emotional damage to victims.
Prior research on online romance fraudsters provides a preliminary understanding of the operational features (stages and persuasive techniques) and their modus operandi. However, the objectivity and relevance of the victimization data in explaining offenders\u27 behaviors may render those studies may represent significant drawbacks. To overcome the limitations, it is important to use actual offender data to generate meaningful analyses of romance fraudsters\u27 behaviors. Consequently, this dissertation aims to use experimental data similar to that applied in my previous work (Wang et al., 2021), combined with existing criminological and communication theories, to promote a better understanding of romance fraudsters\u27 behaviors in the online world.
This dissertation begins with a scoping review of the current online romance scam literature, intending to use a scientific strategy to address the existing scholarly gap in this field of research. Derived from rational choice theory, the criminal events perspective, interpersonal deception theory, and neutralization theory, the second and third paper uses an experimental approach to assess the influence of rewards on romance fraudsters\u27 behaviors. The three papers\u27 results demonstrate the rationality of online romance fraudsters when facing rewards. Moreover, such rationality can be explicitly seen from their uses of different linguistic cues. Finally, the outcomes provided in the current project also provide policymakers the information about the rationality and modus operandi of fraudsters which can be used to identify the behavioral patterns at an early phase to prevent significant harm to the victim

Construal in expression : An intersubjective approach to Cognitive Grammar
This doctoral dissertation is a metatheoretical survey into the central semantic concepts of Cognitive Grammar (CG), a semantics-driven theoretical grammar developed by Ronald W. Langacker. CG approaches language as a semiotic system inherently structured by certain cognition-general capacities, and it defends a usage-based conception of language, therefore denying the strict dichotomy between language and other realms of conceptualization and human experience.
For CG, linguistic meaning is thus defined relative to our general cognitive and bodily disposition, as well as to the contents of experience the former structure. The cognitive and experiential aspects of meaning are described relative to so-called dimensions of construal. In this study, I will provide a systematic critical account of the theoretical explanation Cognitive Grammar provides for the dimensions of construal.
The point of departure will be in social ontology of linguistic meaning developed and defended by Esa Itkonen, who has accordingly criticized Cognitive Grammar for inconsistent psychologism. According to Itkonen, linguistic meaning is an object of common knowledge and cannot be reduced into an individual s conceptualization; the dimensions of construal capture experiential meaning that is part of language as a social semiotic resource. This entails that linguistic semantics assume as its object of description non-objective, perspectival meanings that are commonly known.
It will be argued that the usage-based nature of CG provides a way to release this tension between objective and non-objective aspects of meaning by explaining how perspectivity of semantics results from the acquisition and adjustment of meanings in actual discourse. This, however, necessitates an ontological revision of Cognitive Grammar and rehabilitation of the sociality of a linguistic meaning, which is the topic of this study.
In addition to the work by Itkonen, prominent socially oriented cognitive linguists, such as Jordan Zlatev, have emphasized the necessary intersubjective basis of experiential meaning. Within the Fennistic studies, on the other hand, the intersubjective approach to CG and Cognitive Linguistics in general has taken the form of combining cognitive linguistic methodologies with Conversation Analysis.
This study combines elements from both of these approaches in order to provide a comprehensive assessment of the notion of construal in CG. In so being, the main task of this study is to critically evaluate the cognition-based explanation for the dimensions of construal, provide a socially grounded alternative, and apply the alternative into analysis of construal in (written discourse).
The thesis demonstrates that the dimensions of construal are not dependent on the aspects of cognitive theory on the basis of which they are argued for. Instead, the notion of construal is shown to be inherently intersubjective and context-sensitive. Construal captures aspects of semantic organization that are correlates of intersubjective alignment between conceptualizing subjects in a given discursive context.Kielellinen merkitys sisÀltÀÀ vÀistÀmÀttÀ jonkinlaisen nÀkökulman siihen, mihin kielellinen merkki, kuten sana tai syntaktinen kokonaisuus, viittaa. Esimerkiksi ilmauksia avohoitotapaus ja mielenterveyskuntoutuja voidaan kÀyttÀÀ sujuvasti samasta ihmisestÀ tai ihmisryhmÀstÀ, mutta silti niiden merkitys on eri. EnsimmÀinen vaihtoehdoista ilmaisee suoraan erÀÀnlaisen hoitopÀÀtöksen synnyttÀmÀn kategorian (avohoito-) yhdistettynÀ kokonaisilmauksen alentavuutta alleviivaavaan pÀÀsanaan (-tapaus). Toinen ilmauksista taas esittÀÀ kuvatun ihmisen aktiivisena toimijana, joka itse työskentelee terveytensÀ parantamiseksi.
Merkityksen nÀkökulmaisuus voidaan mieltÀÀ ilmaistun asian tai asiaintilan ja kieleen kirjautuneen kÀsitteistÀjÀn vÀliseksi suhteeksi: asiaa tai asiantilaa ikÀÀn kuin tarkastellaan jostakin sijainnista kÀsin kielellisesti. Toisaalta nÀkökulmaisuus on kaikille kielenkÀyttÀjille yhteistÀ tietoa. KielitieteessÀ teoreettisena haasteena on pitkÀÀn ollut se, miten tÀmÀ nÀkökulmaisuuden ja jaettuuden yhdistelmÀ voidaan selittÀÀ ja kuvata johdonmukaisesti merkityksen tutkimuksessa.
TÀssÀ vÀitöstutkimuksessa otetaan kriittiseen tarkasteluun kognitiivisena kielioppina tunnettu teoreettinen kielioppi ja arvioidaan sen kykyÀ selittÀÀ ja kuvata merkityksen nÀkökulmaisuus kÀsitteen konstruointi ( construal ) kautta. Konstruointi kÀsittÀÀ joukon ulottuvuuksia, joiden arvoja muuttamalla sama asia voidaan ilmaista lukuisin eri tavoin: esimerkki-ilmauksissa yllÀ vaihtelee vaikkapa se, mikÀ viitatusta ihmisryhmÀstÀ profiloidaan eli tuodaan ilmauksen ilmitasolle. Tarkkaan ottaen tutkimus kÀsittelee nÀiden eri ulottuvuuksien teoreettista perustelua ja toisaalta sitÀ, kuinka koherentteja ne ovat kuvauskÀsitteinÀ.
VÀitöstutkimus osoittaa, ettÀ konstruoinnin ulottuvuuksien avulla voidaan kuvata tehokkaasti ilmausten ymmÀrrettÀvyyden kannalta vÀlttÀmÀttömiÀ merkityspiirteitÀ. Toisaalta konstruoinnin ulottuvuuksien teoreettinen perustelu on ongelmallinen. Kognitiivinen kielioppi pyrkii selittÀmÀÀn konstruoinnin ulottuvuudet yksilön kielellisen prosessoinnin ominaisuuksina, mikÀ on ristiriidassa kielellisen merkityksen jaettuuden kanssa. VÀitöstutkimus osoittaa tÀmÀn selitystavan loogiset heikkoudet ja esittÀÀ konstruoinnille vaihtoehtoisen perustelun. TÀssÀ perustelussa konstruointi esitetÀÀn ensisijaisesti sosiaalisena, ilmauksen ymmÀrrettÀvyyteen ja kohdennettuuteen liittyvÀnÀ ilmiönÀ
