A highly structured description of entities and events in histories can support flexible exploration of those histories by users and, ultimately, support full-text digital libraries. Here, we apply the Basic Formal Ontology (BFO) to structure a passage about the Roman Constitution from Gibbon’s Decline and Fall of the Roman Empire. Specifically, we consider the specification of Roles such as Co...

The ancient Greeks observed that men heavily exposed to lead became sterile. But this knowledge was not passed to the Romans, who stored their drinking water and their wine in lead-lined containers. Romans also added lead to some of their drinks as a sweetener. Based on examination of lead in Roman bones, some historians conclude that the Roman upper classes probably couldn't reproduce themselv...

Given a graph $G=(V,E)$ and a vertex $v in V$, by $N(v)$ we represent the open neighbourhood of $v$. Let $f:Vrightarrow {0,1,2}$ be a function on $G$. The weight of $f$ is $omega(f)=sum_{vin V}f(v)$ and let $V_i={vin V colon f(v)=i}$, for $i=0,1,2$. The function $f$ is said to bebegin{itemize}item a Roman ${2}$-dominating function, if for every vertex $vin V_0$, $sum_{uin N(v)}f(u)geq 2$. The R...

A Roman dominating function (RDF) on a graph $G$ is a function $f : V (G) to {0, 1, 2}$satisfying the condition that every vertex $u$ for which $f(u) = 0$ is adjacent to at least onevertex $v$ for which $f(v) = 2$. A Roman dominating function $f$ is called an outer-independentRoman dominating function (OIRDF) on $G$ if the set ${vin Vmid f(v)=0}$ is independent.The (outer-independent) Roman dom...

Information is stored and exchanged in the form of streams of characters from some alphabet. An alphabet is a finite set of symbols, such as the lower-case Roman alphabet {a,b,c,...,z}. Larger digits may be formed by including the upper-case Roman letters, punctuation marks, the digits 0 through 9, and possibly other symbols such as ‘$’, ‘%’, etc. In the other extreme, we may choose the simples...
